Better late than never, here's mine (after an update of your branch). Most are 
details (but then again that's where the devil lies :-) ).

The chord editor :

- some layout nitpicks : buttons on the right look too big, I'd stack them on 
the bottom of the dialog. It's also probably better to disallow resizing of 
the dialog.

- the scale names with "_Sharp" or "_Flat" would look much better with actual 
'#' and 'b'.

- I'm not sure the scrollbar is the right control to select the fret number of 
the fingering, a spinbox would probably be more appropriate, and strange 
things sometimes happen when you set open strings along with a barré, and 
then use that scrollbar.

- the fingering editor itself still needs work. There is no way to remove a 
dot (except by adding one on another fret on the same string). When "drawing" 
a barré, there's no visual feedback of the mouse move. It lets you add a dot 
(and even a muted or an open string) *behind* a barré.

- it's possible that eventually you'll have to support custom tunings, but I 
wouldn't worry about it for now.

- I'm not at all comfortable with the Scale/Modifier/Suffix  representation of 
a chord. That's my biggest gripe. I'm sorry if this was already discussed and 
I glanced over it, but as a guitar player this really doesn't make sense to 
me. A chord should be defined with a tonic, an "extension" (can't find a 
better term), and an altered bass.

For instance with your current scheme I don't see how I can make the 
distinction between a C7 and a Cmaj7. Also, it doesn't make sense to let one 
add any kind of "suffix" after a 'sus' (only sus2 and sus4 exist) or a 
'dim' (only dim or dim7). It lacks 'add' (Cadd9, Cadd11 - or is that 
'plus' ?), and finally you can add only one modifier while in practice you 
can have two (C7sus4, C6/9, Cmaj7#5). I suggest you take a look at a chord 
dictionnary before going on, I found this one to be rather good :

About the chord selector :

- apparently some of the fingerings are wrong, and some are missing, like the 
A form for C major (x13330).

- same comment about the buttons than with the chord editor, layout probably 
needs some rethinking, the aliases field is probably too large too

- 'Create' should be 'New' I think

That's about it. The chords display nicely over notation, which is probably 
the hardest part to get right, so I wouldn't worry too much about the 
rest. :-)
