Middle click to close tabgroups

[Jean BAUMANN]

Hi,

Whenever I open two tabs on the same subject, I group them (I even released an extension for that but that's not the point). The problem I face now, is that closing a tabgroup requires to right-click on the group and go to "Delete group". This is painfully slow and I think could be made much much easier by copying the way to close a simple tab: middle-click on it.

Would it be possible to implement this ? Thanks a lot and sorry for my poor English.
