Filled label colors and menu background color
I would like the label colors to be filled and not have this other border colors. Would be more consistent.
Also it would be nice with a brighter tone of the background color in the left menu. A greyscale instead of the current all black.
See attached image. From left: Spotify > Sparrow Mail App > Airmail 2.5.
With that, a slightly thicker font that's easier to read on the dark background. Again, compare with Spotify and Sparrow mail.
