Alternative group view
I like the innovative way beem displays groups. But it's not very handy in practice if you are used to other IM clients (Xabber, Pidgin, ...)
The problem is, that you see unwanted online-contacts in the "All contacts" group where you normally would collapse the group. (e.g. i have a special group for transports that are always online).
An configurable additional/alternative view with all groups in one window where groups could be collapsed would be a nice feature.
