Ability to collapse groups

[isontheline]

Hello,

Thank you very much for your good work on this app. Is it possible to add a button in the group view so I can collapse the group. I have many groups and many more connections saved. Sometimes I can't find the right server via the search field and then search manually in the overview. Collapsible groups would make the search much easier.

Many thanks & best regards Robert
