For the visually imparied, the application colors are a total no-go!
The new fonts for messages were a great help and works perfectly. Thanks for the custom setting in 2.5.
What is missing now is a simple dark mode for the application itself. Dark background with White text. Just a simple switch which turns maximises contrast.
Please no more lighter or less light colors. Also compatibility with Windows High Contrast Black mode would be awesome. Remember, message fonts and colorsettings are awesome. It is just the application buttons and text now.
