Holy Aqua Interfaces Batman!
Open source projects seem to consistently have poor UIs. And before anyone jumps me, yes I have been involved in interface design on open source apps. Maybe it's a matter of taste, but the current interface looks like a bad Aqua app from 10 years ago. Jelly bean buttons? Seriously?
And to put my time where my mouth is, if any of the developers are reading this and want help contact me. Not a deep coder but have done UI layout in the Mac/iOS world. If you think it's fine as is, then we should agree to disagree.
