[Wish] Autojump cursor in Custom columns config

[fenix_productions]

Hi.

When user opens Custom columns configuration window he can easily move some fields up and down by clicking on proper buttons. When he does that mouse cursor jumps according to clicked entry.

Such behaviour does not happen for adding and deleting columns.

When I want to add few fields I have to click on Add column button, move down mouse and click again. Similar for deleting.

My wish is to have cursor placed on button's new position to avoid unnecessary moves.
