Dark mode?
I’ve been using Paprika for years now. It works really well and has all the features I need. It works with Apple’s family sharing, so other family members can access it, too. Highly recommend.
I use it with Dropbox. I haven’t noticed any data loss. I’ll have to investigate.
Snapdrop is great. I don’t need it often, but when I do, it’s so simple and easy to use.
You can head over to the ArchiveTeam Warrior site for more info. You can set up a Warrior instance in Docker and assign it to the Reddit archive project.
TubeArchivist sounds like a better fit for that.
