I just found this awesome little that that has settle my desire to jump back to windows when i saw the new Taskbar for Windows 7. The app is Fantasktik. http://www.docklandsoft.com/fantasktik/ In it's first release, it didn't support space but as of about 2months ago it has. I do like the preview of the window but it not too crazy about it. I love the dock (had one on winXP), but there just a few to many things not working they way I'd like. First thing that comes to mind, It doesn't show you all the windows open of an app but only that app is running. Another the osx doesn't do well is the alt+tab and the lack of window support. I know there's Witch but it sometimes has a delay before shows the list appears. some that works for me is using Witch for cmd + ` window switch so i can get an windows list. yes, i know you use use Expose then tab to see all the windows but that only in one space and with all the space visable the windows get much smaller and hard for me to see them. btw, anyone who trashes this app for being too windows like, well go look at KDE and Gnome. Anyone else have any good tips on windows switch? or maybe some other task bar stuff?
