You can already download YT videos in LibreTube and NewPipe, speaking about NewPipe, I would suggest using NewPipeSponsosblock for blocking in video sponsors from creators. Aves Libre is a better advanced Gallery alternative with EXIF editing.
Aimp is a good alternative to Retro.
Spotiflyer is an alternative Murglar.
Schildi Chat is a better alternative to Element X, its based on Element but is a lot faster and has a lot more options.
Ps: I’ve been seeing a lot of posts and comments by you in the communities that I follow, just want to tell you thx for contrubuting to them xD.
