I've released another update. This update adds the chord functionality I wanted. I still haven't tweaked the GUI to use dropdowns, that will be in my next update. With the chord drawer opened this program is eating up a bunch of screen space so I may just tweak the UI and release that as an update.
Anyway, program description, screenshot and download link can all be found
here.
I'm still open to suggestions if anyone wants to add them in this thread.
