Comment 6 for bug 374274

I'm concerned that adding patterns to the folder exception box will be confusing. I guess you could change the icon for patterns or something but I think it would be hard to be clear about what they are and, more importantly, I can't think of any other applications that do it that way. At that point you're digressing from standard UI practices like consistency and following expectations.

One thing to note when looking at my mockup is that it isn't clear that the patterns apply to file exceptions and not inclusions. We'd have to tweak the mockup to fix that - perhaps retitle it more appropriately or surround the entire "exceptions" section with a line. Minor stuff if it's the direction you want to go.
