TOMECK  I agree that PTHPasteboard is a fantastic clipboard/pasteboard enhancement but that there are still ways to improve it. However, it might be interesting for you that you can edit the clipboard entries of a custom pasteboard at least. Maybe it would be a solution to implement the same feature into the main pasteboard.   
(Version 4.4.1)

LARRYMCJ  Additionally, this developer simply does not answer support questions. I've emailed him three times now over the past three weeks and have not received a reply. I like a lot about PTHPasteboard Pro, and even though I purchased it...I am quickly falling out of love with it. The least a developer an do is address concerns and problems voiced by registered users.  
(Version 4.4)

TOMECK  Again, I am not sure what you are talking about; maybe I misunderstand your complains:

1) It is possible to DELETE clips from a secondary pasteboard and even more to EDIT them (inside the pasteboard itself). Open the window of the secondary pasteboard and hit the pencil icon. You will get a split window which allows you to add (+ button) and delete (- button) clips and in the second part of the clipboard window you may edit text clips. You may also rearrange the clip order by drag and drop the clips.

2) That is partly true. I haven't found a way to send clips from a secondary pasteboard to a third pasteboard in one step. However, you always may send clips back to the main pasteboard and from there to the third, fourth, fifth... pasteboard.

Hope that helps,

TOMECK

LARRYMCJ  @TOMECK: the delete issue I figured out. The other is still a problem. To simplify my problem example, try to MOVE any clip from a secondary pasteboard (not the main one) to either another pasteboard or even to the main pasteboard...it's not happening. I need to have several pasteboards and I need to be able to move clips between them. I understand how to edit them, etc. You're supposed to be able to drag and drop clips between pasteboards, but each time I try it the app shuts down. I did finally get in touch with the developer and he's hopefully working on it. He is VERY slow in answering email.  
(Version 4.4)

LARRYMCJ  @TOMECK: just to clarifky, the developer specifically told me that all I have to do is drag clips back and forth as desired between pasteboards...that is what I can't get it to do.  
(Version 4.4)

TOMECK  I am glad to hear that you got a response from the developer and that some of the issues are sorted out.

Regarding your drag & drop issue: I can't reproduce a crash at my end (using OS X.5.6 and PTH Pasteboard 4.4). Perhaps it is something specific to your system? I cross my fingers that it will be fixed for you soon. In the meantime it might be a work around to use the "Copy to main" function to send clips from a secondary pasteboard to the main pasteborad at least (that means pasting from a secondary pasteboard will copy the clip to the main pasteboard).

However, I am with you that a function to send items from one to another pasteboard without opening the window of the target pasteboard would be a nice improvement; maybe the same possibility like in the main pasteboard to send items through the context menu.

LARRYMCJ  "However, I am with you that a function to send items from one to another pasteboard without opening the window of the target pasteboard would be a nice improvement"

This is what confuses me the most...I am looking at an email from the developer that clearly says this is already a feature...but it's not. If I open two pasteboards on my desktop and try to drag and drop...either it just doesn't happen, or often the app crashes.

I highly doubt there is anything wrong with this machine. I just retired from 20 years in the computing business and am pretty much a bonafide geek. Plus, it's new, not a lot of apps on it, and I'm not having any other problems, but it could be possible I guess. That aside...the drag and drop feature simply doesn't exist.

I really need that feature, so I better start looking at other clipboard apps and just chalk up this registration to experience. Thanks for your help.  
(Version 4.4)

TOMECK  You are welcome - I am glad if my response was of some help. Be assured, the drag & drop feature exists and it works for me smoothly. Drag & drop between two secondary pasteboards moves the clip, and drag & drop from the main pasteboard to a secondary pasteboard makes a copy. I would like to show you this with a small movie but MU doesn't allows any uploads and PMs...

Just for the record: I am not affiliated with the developer at all... ;-)   
(Version 4.4)

LARRYMCJ  I never thought you were affiliated with the developer...your replies are way to fast :-)

FWIW, I unistalled the Preference Pane for PTHPasteboard and trashed all it's associated files. I then reinstalled it and now it's working. So something must have gotten munged during the first installation because now drag and drop is working between pasteboards (whether EDIT is turned on or not) and it's not crashing.  
(Version 4.4)

LARRYMCJ  Last thing puzzling me about this app is when you have lots of clips in the main pasteboard, how can you view the entire text of a single clip? If I left-click it copies it and closes the main pasteboard...if I right-click I get the a context menu that doesn't help me. On the secondary pasteboards I can left-click and hold and I get the yellow pop-out window with that clip's full text...but this doesn't work on the main pasteboard. Sorry to bother you.  
(Version 4.4)

TOMECK  Never mind - Have you tried to mousing over the clip and wait for a couple of seconds? This should bring up the yellow pop-out window with that clip's full text in the main pasteboard as well.

Also you may like to try to adjust the numbers of clips displayed in the main pasteboard because that leaves more space for the clips and it is easier to identify the right one. In addition check out the "Show as Compact Text" and "Always Show as Plaintext" options by adjusting the "Plaintext Font" (-> Pasteboards -> Advanced...).  
(Version 4.4)

LARRYMCJ  That's it...thanks! It takes about three full seconds and I just wasn't waiting long enough. Odd that displaying clips behaves differently in secondary pasteboards. Anyway, thanks for all your help...I appreciate it.  
(Version 4.4)

TOMECK  It seems you have overseen some of the (incredible many) functions oft PTHPasteboard because it IS possible to delete single items from the clipboard:

Open the clipboard, choose a item, click the right mouse button, choose "Delete item" from the context menu. There are other ways to get the same result (in particular useful for people who are preferring to work with the keyboard) like using the Main menu or the Small Main menu. However, it might be an idea to allow to delete a single item just by hitting the backspace/delete key.

To your other point: It might be useful that you get a warning if you are going to delete the clipboard history but if you hoover the mouse over the rubber it clearly says that it will delete the (whole) clipboard history.  
(Version 4.4)

LARRYMCJ  @TOMEK: You are absolutely correct and thanks for pointing it out. I do realize that mousing over the eraser displays a "Clear Pasteboard History" tutorial, but even on the fastest of Macs it's three seconds before it displays and not having the interstitial warning sort of goes against most developmental standards. I just think it would be a small effort to add and make the best of this genre software even better. I've sort of solved this anyway by adding a "Boilerplates" clipboard and now put anything I want to save into this, so if I accidently delete the Main clipboard it's not a big deal. I will purchase this anyway...since there isn't anything remotely closet to it in functionality.  
(Version 4.4)

LARRYMCJ  I'm glad I'm not the only one to see this. I absolutely HATE the look of this app. Most Mac users are perfectionists and want applications they pay good $ for to look as good as they perform. PTHP is very functional...but is truly ugly!  
(Version 4.4)

TOMECK  Are you really reviewing a (perfectly working) utility app and detracting two stars only because the GUI is ugly in your opinion?
