Yeeeeaaaaahhhh!

That’s the way. And thank you, Linux, for not asking bugging me again later… ever.

XnView is quite feature-complete for my needs, but it’s constantly trying to phone home to Google, so better run it in a sandbox.
Geeqie is better in several ways - e.g. it supports avif and jxl - but it’s missing some features I’ve come to like.
I’ve yet to try qView.
