I think I read somewhere that ObjectDock and ObjectDock Plus are not part of the master plan and will be phazed out.
'I think' and 'somewhere' being the key words
I currently run objectdock plus over my two monitors, and it is brilliant! I use six docks
1 + 2 ) are at the bottom center of each screen, they have start menu, recycle bin and the clock on them.
3 ) is at the bottom right of the left screen and has my system tray on it (it's got the smallest icons and it stops from cluttering any others up)
4 + 5 ) are on the left of the left screen and the right of the right screen, they have my open windows on them (clear background)
6 ) is a tabbed dock at the top of the left screen, it contains all my icons arranged neatly and categorically.
On objectdock I wouldn't be able to use a tabbed dock, and I would only be allowed one dock. It would ruin my screen.
