As (most unfortunately) IE is, desperatly need rand (like in grid) for

…And any component that recieves config via subrequest?..

Aaaand as an improvement:
Toolbar desperatly needs 3 features:
1 - password item… If it would have one, a LOTs of stuffs could be done without unneeded forms, just with toolbars…
2 - Height parameter… Had to patch css for it )
3 - Alighn to different sides… Like 3 buttons on left side, and 2 on right…

That, as far as I think, would make things be a lots better )
