I'm currently investigating ExtGWT for the feasibility over replacing our existing grid control.

So far, the grid control looks quite impressive and satisfies most of our requirements.

However, there're several features not supported out of the shelf.
Below is the list of them.

Feature Supported
(3.0 beta2)
Column freeze No Suggested work-around. link
Icon in the row header No
Advanced mouse buttons. 4~6th button No GWT supports it?
Bar-less scroll bar ?
Time edit field (up/down arrow buttons) ?
Footer No

Is my findings correct?
