No need for manual ytdlp! I use TubeArchivist[1] to download channels and then share them with kid's account on Plex. I'm surprised it hasn't been mentioned yet. Great self-hosted solution.
An excellent game where the designer/programmer doesn't let things get in the way of building is Aurora 4x [1] (not really a small game anymore). Only runs on windows, doesn't even have modifiable window sizes. For users that have period separators instead of commas a bunch of the text is cut off. It's a fantastic game that is purely what the creator wants and plays and is nothing more, and it has a great community behind it. It is purely a work of passion by the creator.
I would recommend Simple Tab Groups [1] for Firefox. Then you can have as many sets of tabs you want (with detailed names), that are backed up in case of crashes etc. They are also out of the way when you don't need them, no managing multiple windows. Easy to delete groups, or keep them for later.
Taptap looks really cool and I would like to use it, unfortunately my workplace doesn't allow 3rd parties to store the information that would be in my notes. Have you thought about a self-hosted version?
I think it's definitely on the right path. You can see the developers daily changelog[1] and there's also a great modding community already started[2].
If you think Dwarf Fortress is cool, check out Rimworld[1]. It's still in alpha, but it's already a playable game. It's basically a sci-fi Dwarf Fortress (and it has a way better UI).
