Sources section is too small

Allow it to be resized somehow.

Ping on this. Would love if the source selection list was resizable. I've got about 50 different MIDI devices on my system and there's a lot of scrolling in a 6-line tall window to find the right one. Even worse because the source and destination names are usually the same so it's hard to tell which section you're in.

+1 from me as well... also have a large MIDI setup and would love to be able to see things in a larger section.
