That really bugs me too, did you voted for the bugs?

Did you thought about another UI-Design I always ask this because IMHO 
no user can deal with thousand of items at a time.

This is not right any more since JFace 3.3 introduced Grid-like support 
for SWT-Tables/Trees. See

KTable comes to my mind. It has many features but I haven't used it 
myself. Did you asked for dates on the nebula list, I think I can 
remember Chris saying he wants to release the Grid-Control together with 
3.4 but I could be wrong.

To me the Grid code looks fairly stable and I would use it in production 
code if I would have a need. I use other controls from nebula (like 
PGroup and PShelf and they work on systems supported by SWT).

The good thing if you are using stay with Grid/Tree is that they are 
both supported by JFace.
