Not sure if this has been suggested before, but:

Would like to see a level filter on chat forwards. I have a spam filter, but it seems that Jamba forwards before the spam add-on filters (bad-boy in my case) - I wouldn't really need a spam filter if I could simply specify to filter out all messages from characters with a level lower than 10 (or whatever) - would be great and save me an add-on.

Also, I'd love to see an option to switch off jamba. I realize that this can be done in part with profile, but not completely. Rigth now I use ACT to do that, but it would be nice to be able to macro it.

Also - great work, love the add-on - especially the macro functionality is brilliant!
