When importing a project to CVS, a wizard step to allow the user to review and add/remove ignored files.

UI should be simple and something like the following:

+-[Ignored Files]---------------------------+
| +------------------------------+          |
| | bin                         ^| [ Add  ] |
| | *~                          || [Remove] |
| | *.bak                       v|          |
| +------------------------------+          |
+-------------------------------------------+

This screen should scan the subfolders and auto populate with defaults such as ignoring *.bak, *~, *.java etc.

Another option that would be useful for each entry would be a check box that allowed the ignore to not add to .cvsignore
and to only ignore during the import.

I use NetBeans for managing external projects (.NET), therefore I generally use the Favourites tab.
