I think I can safely say ObjectDock Plus is the app I have the most interaction with on the desktop. I say that because it’s how I launch most of the applications I use during a given day. I have some in the Windows 7 taskbar, but those are mostly browser and e-mail apps. Everything else is stuffed into tabs in ObjectDock which I organize by category.
For example, I have tabs for the games I play and another for my Adobe apps. Along with several others tabs.
Do you organize yours in a similar way?
