Already requested before, but with Win 10 any chance to colorize the textshadow of inactive buttons for real dark themes (I'd like to have a dark color-scheme like Photoshop offers, but the shadow is not darken enough, so it looks ugly)?
And also for the column-background on top of lister and color statusbar edge 
.
These 3 color-settings (but esp. textshadow!) are the only one left to design DO in every color-scheme you can think of w/o looking bad!
