Since I have not seen it yet in the comments, I use Floorp, a Firefox fork with some nice UI improvements (and apparently some performance improvements, but both are very fast for me).

Thanks! I had not heard about it.

It seems to only consider GNOME as the official DE and seem to not have the “blend” integrations of different distro.

Might not be for me but I appreciate the reply and it might help others.

I’m in the same boat, Kinoite (or rather my own blue build of it) killed my distro-hopping. But fans of Arch might be interested in the upcoming immutable arch-based OS: BlendOS

Thank you for sharing.

If the pictures are from the same origin (like if your camera was on a tripod) you could use astronomy software (look for image stacking) to denoise and attain a better image quality.

You can absolutely install it on a USB drive.

But to do so, you need to boot up the installer and proceed with the installation process from your (other) USB drive. AFAIK there is no live+persistent mode on the official ISOs.
