CTableTree (and viewer) +1
SearchHelper - 0
CButton -1

Nebula is about supplemental widgets for SWT.  It doesn't mention JFace, however, many people would like both the widget and the associated viewer.  As long as they are in a separate package and the widget has no reference to the viewer, I don't see why the viewer can't be included.

Thanks for contributing!

Hi Jeremy,

Again, I have to ask you the same things I asked Emil.  I just want to
make sure we wont have any legal problems with the submissions after
they're voted on.  You are the only author for the submission?  If you
are not employed by an Eclipse member company, will your employer be
willing to sign an IP waiver?

CTableTree (and viewer), SearchHelper - +1

CButton seems to wrap a normal Button?  I'm confused by the design.  I'm
also not sure that it provides enough features above and beyond a normal
Button (especially now that Button can display an image).
