DAVERMONT  The Release Notes available from the Q menu say:

Fixes For Plug-ins and App update  
(Version 1.0b54)

DAVERMONT  iKey 2.2.2 does work with Leopard, but you will need to reinstall it.  
(Version 2.2.2)

DAVERMONT  I really missed Saft for the first three days after installing Leopard. The program improves Safari in so many ways it's amazing. The best feature for me is the shortcuts; to search MacUpdate for saft I simply type: mu saft

Having the Enter key be a shortcut for the Next link on a page is a big timesaver as well. I only wish it would work on links that *start* with Next, as many sites use Next Page, or Next >>, which Saft ignores.

I used to use the autosave tabs a lot, but not so much anymore. Some people will find that handy.

The ad filtering isn't as sophisticated as PithHelmet, but it does a decent job. Saving a web page as a single PDF page is handy sometimes (print as PDF still saves a multipage PDF when you need that). Auto-hiding the downloads window is another nice feature. Downloaded files contain the URL of the web page in their Comments field, making it handy to go back to that page if you need to.

Again, lots of useful improvements to Safari, well worth the $12 price.   
(Version 10)

DAVERMONT  You should have gotten a confirmation email with a link to the new download; the url will have the word "leopard" in it, and it works fine with Leopard.  
(Version 10)

DAVERMONT  Looks promising, easy to understand, setup and use. But it's crashed on me a few times so I can't trust it yet.

The Good: It's easy to set up new projects and action items, and assign a contect (and due date, if it has one). Also easy to drag and drop items to rearrange them, or change a context. The three different views are useful: by project, by context and by due date.

The Bad: It's crashed on me a few times. Once a project had somehow gotten itself both at the top level on the shelf and within a larger project (Work) and WTD kept crashing until I deleted that project and recreated it only within the Work folder. Another crash was when it had problems with a newly created context (agenda) I had assigned some tasks to, and that context did not appear in the Context view (it crashed at that point).

Wishes and Gripes: It would be great if it could export a calendar file that iCal could subscribe to (like Thinking Rock). It would also be nice if one could set a due date without having to set a time (anytime Tuesday). I wish I could change the default time to something other than 6pm. The context popup should be alphabetical. Preferences and Help should be in place before the author starts asking for money ($30 in this case).

Summary: Looks promising, but not yet ready for prime time.

Note to the developer: This could be a great app, definitely keep at it. Test it more and fix those crashes before you ask people to pay and trust their lives to it.  
(Version 1.0)

DAVERMONT  Great desktop manager, I've been using it about a year now and am generally pleased with it. One quirk I've noticed is that you can't use the keyboard to switch out of a screen where Parallels is running; there's a new option that supposedly fixes this, but the option doesn't work for me (and doesn't even stay checked for some reason). The problem may very well be that Parallels is eating all keypresses (and VD isn't seeing them), but the net effect is annoying.

Other than that, VD has been well behaved and is a joy to use, I find it even better (and far more portable) than using a second monitor.  
(Version 0.53r260a)

DAVERMONT  Great program for choosing colors and color schemes, even better now that it's a Universal Binary. If you work with colors at all (especially for a living) it's well worth the $15 they're asking for it.  
(Version 2.1)

DAVERMONT  I used (and loved) Acta for years on pre-OSX Macs and still have many dozens of outlines in Acta format. Thanks, A Sharp, for creating an OSX version of that wonderful app!  
(Version 1.0a1)
