Just of the top of my head discovered today.

Not a GUI as one exists. But a more configurable one as it is crap for visually impaired.

Rpi-imager gui dose not take theme indications for font size etc. Worse it has no configuration to change such thing.

Making it pretty much unsuable for anyone with poor vision.

Also it varies for each visually impaired indevidual. But dark mode is essential for some of ua.

So if your looking for small projects. Youd at least make me happy;)
