Starting with someone’s dotfiles is a much better way to start with these minimalist window managers. You can see what they did and only tweak the the things you want to work different. Still not as easy as a DE’s unified settings, but if you like that fine grained control it can be worthwhile. My setup is quite basic, but having everything bound to the keys I want lets me do what I want quickly.
Libredirect in general is fantastic, a lot of shit websites become so much more usable. In particular not having to use Fandom is a godsend, that website in particular is just awful.
it uses barely anything. youtube-tui is a TUI not CLI, you can click on shit and it’ll run on hardware that for some reason cannot handle freetube of all things. you will have to set up mpv or something for most leaner alternatives to get video running on hardware that modest.
