Here's some feedback for the new v1.98 update:
1. Window thumbnails work much better.
2. I like having the Aero peek functionality.
3. I wish system tray icons in a dock, when clicked on, would behave the same way they would in the taskbar. ie- the volume icon. In W7, when you click on the volume icon in the taskbar, the volume slider pops up. When you click on the volume icon in the sys tray dock, nothing happens. You have to right click, and then you get other options, but not the normal functionality.
4. Idea: The start menu is still borky. I can live without the start menu, since I find everything else through my docks. However, one thing I love is the start menu search. There is already a docklet for web search, and I am wondering if a docklet can be developed to bring the start menu search to the dock?
5. How about a shut down menu docklet?
All-in-all, this is a very good update. Good job, Jeff!
