We currently support double-clicking in the panel as a goto-command. Maybe we could reduce that to simple clicks, and then generally just follow the cursor in the panel.

Basically reducing the need for mouse interactions. We could then explore how the panel could get keyboard focus just by using the keyboard. (ctrl+ka only opens the panel without focusing it.)

Technically that means we implement on_selection_modifed for the panel view. Since the target view also implements on_selection_modified to scroll and select the correct error in the panel we need to take care of this circular triggering which will be the tricky part here.
