Bug 11863 Update Test Suite action does not allow to remove
What the action actually does is RECREATE the test suite based on the selection in the dialog. I do an update on a test suite which contains X. It is no clear that if I only select Y in the dialog that I'll end up with X being removed. Normally "Update" shows the content of the existing stuff (dir, zip) and allows to modify this. I think renaming the action (and the dialog) to Recreate Test Suite would solve the problem.
