Branches View: quick-search should support paste from clipboard and standard text editing features

I found a very very strong drawback in your "Search for" form (appears not by hotkey or menu, but automatically as you type) in "Branches" View.
This form is absolutely incompatible with copy-paste!
Just try to find branch in "Branches" view using "Search for" and pasting required text from clipboard.
I tried several ways to workaround this strange behavior but everything did no work well.
If you type branch name manually - it works OK.
If you try to paste branch name or even part of branch name - it does NOT work.
Besides incompatibility of "Search for" with copy-paste from clipboard - it's also incompatible with standard text editing (for example, try to use left and right arrows to navigate in search text and edit it - your panel just disappears automatically).

My recommendation: allow user to make "Search for" permanent or show/hide it by explicit user request (not automatically - this works badly!) - at least it should NOT auto-destruct if I edit search text using standard text editing and it should work with copy-paste from clipboard.
