Currently, there is no easy way to jump into the Branch Explorer from selected branch(es) in the Branches view.

This would be very convenient since it can sometimes be cumbersome to locate a specific task branch etc in the main Branch Explorer, while it's quick to find it in the excellent "Tree view" of the Branches view.

I'd like to have in the Branches view a (partial?) clone of the "Branch Explorer" submenu from the Branch Explorer view:
* Show selected branches in a new diagram
* Show selected and related branches in a new diagram
* etc

Also, when only one branch is selected I'd like a command to simply switch to the standard branch explorer and focus the "head" changeset.
