Black sidebar - allow user to change this. Black is very hard to use
Terrible color to use in general - hard on eyes and fades many folder colors.

Agree, this black is the worst combination you can have, useless in the sun
Let person determine color schemes. I can barely see the icon to start a new email when Airmail 3 is not active on my desktop, Once I click on it, it then becomes more visible.

It would be nice to leave the colorsettings to the user. Personely I don't like that black sidebar, let me set my own colors instead!
Gray text on black background makes it even worse.
