Not really an answer to your question, but I’ll share my approach. Youtube channels have rss feeds, so you can “subscribe” using any rss reader, and don’t need to login.

So I just use firefox with the following addons. A seperate youtube container + adblock + in-video ad skip + age verification skip + feedbro as rss reader.

I like Xubuntu. But I’ve no experience on how well it does with touch screens.

I’ve met people who don’t know what a URL is.

The kind of people that google “facebook” when they want to visit facebook.

Completely flabbergasted that we run internal services not indexable by google.

Had the same issue with outlook last weeks. 60% CPU usage, doing nothing.

For self hosting?

But development seems to have stopped indeed. There is a fork, with new developers, that is actively being worked on: https://github.com/Davilarek/download-navi

GIMP is such a workhorse and a pleasure to work with.
