Dark & light style selector in To Do

We just started the development cycle of GNOME 41 for GNOME To Do, and the first new feature is a dark & light style variant selector:

There’s a lot to be done to make To Do actually useful. The inbox view is essentially useless as it is right now. It really needs more system-wide integration points. The week view could be more engaging and time-oriented than it currently is. I would like to add a command bar too, at some point.

However, we haven’t seen new designs for some time now, and To Do is off from designers’ spotlight for many years now. If you’re design-oriented, we could really use your help!
