and have to agree, the multiple task bar is really nice - I don't get those 3-in-one taskbar icons anymore.
Initially had some troubles with the screensaver-per-monitor, but it seems to be working now. None of the GL ones work though. I have SETI on the main and starfield on the two side monitors.
The move-to-other monitor is nice. The maximize across monitors is useless for me, the monitors are different sizes and resolutions(center 19" 1280x1024 and the sides are 17" @ 1024x768).
