REVOLUTION  After excitedly watching all of the screencasts on the SmileOnMyMac website - I installed this app.

Unfortunately, on the first install - only the snippets ttime and ddate worked (while ignoring all of my other created shortcuts).

I removed the preference pane, and re-installed it. The second time, my snippets worked correctly, until I created my own "Snippet Group". I was unable to move my existing snippets, and saw my shortcuts disappear one by one (deleted, not moved). I then attempted to remove the group, which led to a delete confirmation dialog that would persist even after clicking Delete or Cancel - I had to kill the System Preferences process entirely.

Overall, my experience with this software was nothing like the Screencasts. Although with upcoming releases, I will try it again - as I believe it is an invaluable resource for anyone who sends out e-mails frequently throughout the day.

REVOLUTION  I purchased GarageSale about a year ago. I also purchased iSale, and GarageSale easily leaves it dead in the water. The Developer has done an amazing job with this program, and it is my primary ebay management tool. If the developer adds Inventory Management/Tracking, it will completely replace ebay's Selling Manager Pro.

REVOLUTION  I've just tried out this little app and I'm very impressed! I am trading in Aussie shares and it looks to be working great... My only trouble so far is that I cannot change the "Data Source" from United States to Australia... if somebody else could shed light on how I can do that, it would be greatly appreciated.

REVOLUTION  This software is amazing, and has rescued my 30" monitor which blacks out when attempting to render certain colours. The developer has thought of everything and has obviously listened carefully to the needs of his users. Thanks again!
