We’ve been able to clean it up a bit for the 1.0.6 release. However, it’s really tricky when the resolution is only 16×16 and your company logo is round! It looks great on Retina displays at 32×32.
I’ll cook up a few simplistic designs for the lower resolutions. I completely understand the desire to have a nice clean task bar. I’ll make all of the designs available for folks to drop into the package so everyone has options for customization.
