WNP  This preview of Things looks nice and works fine but lacks many features.

It is essential for a task manger GTD style to be able to grab things from different context (mails from Mail, URL from Safari, link files from Finder, etc.).

Some are on the feature list of Things, but what worry me is that it might take months to get them. There are too many developers who work alone or in very small teams. Once they have finished a product, they start with another and the first one don't evolve. For exemple XyleScope, from the same developer, is a great software but didn't evolve as promised, even in small details, as compare to other author who are very active.  
(Version 0.8.6)

WNP  Same problem here with Saft Leopard. I paid the update but it is unstable, make Safari hang and impossible to print. M. Hao Li do not answered my email.

Another annoying thing is that Saft has to be launched as an application to launch Safari. The problem is that if you open an URL from another application, it launch Safari without Saft.  
(Version 10.0.1)

WNP  As it's not possible to test the app, for the 99 penny I thought go ahead! So did I.

Unfortunately it's a joke! This app launch iCal prior to add the event. So what's the point? If iCal is launched, it's quicker and nicer to add the event directly in iCal.  
(Version 1.0)

WNP  When installing, I checked to add alias in the Dock. It defaulted my Dock so I had to look for my Dock preferences in my backup, replace them and restart Dock.

It's funny how developpers release their products without testing them thoroughly.  
(Version 3.0.4)

WNP  It's a good start but not as reactive as BuddyPop which also offer much more options, like personalize the Address Book fields to display and to search into, call by Skype, send and receive SMS, etc.  
(Version 3.0)

WNP  Looks good, unfortunately I was never able to try it since I got the message "demo version only uninstall the last yank file" (or something like that) lathough it was the 1st time I tried it!

I wrote to the editor and never got any answer. Bad point :-((( I stick to AppZapper, cheaper with a quick and responsive support.  
(Version 1.2)

WNP  Very nice idea and usefull. Bravo! a resizeable windows with resizeable columns would be great to see the all content of the lines and vertically to for less scolling.  
(Version 1.2)

WNP  Not working for me ;-( Does it support international systems (french) ???

On trigger, the action is displayed in the menu bar, but no PDF is produced.  
(Version 1.1)

WNP  Well I also enjoy it but it has a few bugs and moreover the developper didn't upgrade it since more than a year. He spent more time with MenuCalendarClock... probably more profitable!

Now, with Tiger, there are even more bugs (that's I insert an address and it prints with another). I'm looking forward to see an update coming out.  
(Version 1.6)

WNP  Just ugraded through Paypal and cannot download the software. Getting "Account locked" message.

What I hate is that there is no email address, no support page, no way to contact the author. Very bad!
