Who still do more 'dev' work than you all do over at Trollero.
Not if you use your favorite metric of counting commits. We have 880 in our master (not counting developer forks and branches). They have 61.

A GUI is a nice forward facing feature that maybe you focus on if you are trying to attract investors but its really not very interesting or significant compared to the more significant work on the core.
