3 bugs in a cascade

• Oops, was in linguistics mode, where < > can be used to represent letters.
• Only then he saw the 'Edit' button

The first one may be a feature, then it's just for the record:

1. Default Mailboxes/folders can be renamed by /Return/, just like other folders.

2. /Tab/ from a Mailbox does not tab, but acts just like /Return/. From a Source folder, it works as expected.

3. Tabbing includes the +/-/Wheel below the folders. But there's no visible indicator where I am there. Kind of beats the purpose. I'd opt for excluding that area, because the functions are all not so common - but I prefer keys anyway.

Feel free to split them up, of course.

Btw, I think 'Sources' is spot on, but 'Mailboxes' is hard to remember. Well, just an issue if you want to talk about it.
