Taskbar
To me the process of selecting a window from "Active Windows" is slow and inconvenient compared to the "Tiny Apps" process." Maybe this is just, because I have been slow at moving from one to the other. "Active Windows" window should have the option to appear in the last position and dimensions it was and an option to not close on selecting a program,so I could use it as a taskbar. A drag window to "Active Windows" minimisation functionality, your minimise window icon is necessarily very small and hard to click on, also drag application window from "Active Windows" to the position you want would be nice. These are features from Tiny Apps I like, but your Floating Windows app is better in other ways than Tiny Apps.
There is a lot of improvements in new version which is about to come soon. Added features: set size and transparency, disable auto-closing, remember window position and size.
