ENHANCEMENT: Allow resizing of panes so user can have more usable note editing space

I'm accessing ownnote on a portable with a small screen - there is quite a lot of space taken up by the notes list on the left-hand side; more than is needed (the text doesn't actually hit the boundary). I would love to be able to drag the separator between the notes list and the selected note so that I can give myself more room to view/edit notes and less to actually see the list of notes. Maybe even allow collapsing of the left-hand side to maximize the note?
