The nice thing about Free software is that distros can fix these programs that store things in the wrong location. My Debian home is a lot cleaner than my Arch.
I use SyncMe which synchronizes smb shares to your phone. It's great once you have it set up, but it does take a little setup. Gotta have shares and whatnot.
I got a Nazi friend too, believes all that whacky shit. The whackiest conspiracy theory that he believes is that his brown ass is Aryan and that Hitler wouldn't have killed him if given the chance.
Like you mentioned KDE Connect will sync your clipboard between Android and KDE. The KDE clipboard also has a history and you can run actions on clipboard entries which is super handy. I'm not sure about this snippets library, sounds like a permanent clipboard history that you can search, where the KDE one just keeps the last X copied things. I'd rather have my phone keyboard learn words I type a lot personally.
I had sleep issues for years, almost failed high school because of it and then I was late to my own graduation. Now I have a routine that serves me well: Wake up and go to sleep at the same time every day, no caffeine, no sugar at night, nightlight on my monitors at night, listen to boring audiobooks with a sleep timer, don't lay in bed watching TV.
Yes, I am. Any other questions?
