As of 2.2, groups are very limited (that or I'm stupid), allowing only to be like tags for the downloads. They could be used as a way to choose different settings/profiles, like destination folder, bandwidth usage, QM or manual download, etc.

I really like that idea!

I'd also like to see a column in the main window to sort by group. The main reason for this is I don't know if I've missed tagging something. Or just put another field on the right under the groups tab... "untagged"

//hope I didn't miss that request somewhere else, I did look in the forums for a bit

i like this idea also i hate having to organize my downloads and having to put there adress beck in

this is what I would like to see done with groups:
