I know customization comes after functionality on the priority list, but I would love a few color options in the Appearance settings to replace the blue. Purple, orange, and turquoise would be at the top of my list.
I prefer a dark background anyway, so the background would be less of a worry, but a graphite grey and beige would be nice eventually too.
Thanks to everyone that is working on this.
Cherry on top would be dynamic material theming on Android, but I’m not sure it is possible with web apps
