You are right: it does not add much value on its own.  A button is the
way to go, perhaps with its list of branches in a contracted state by
default.  That could also be accompanied by some extra branch-related
commands to make the button's list more useful.

At any rate, that is outside the scope of this bug report.  Please feel
free to close it---sorry for the noise.
