Can share some of my favourites
- KISS laucher
- Floris Board (keyboard, which I love to use)
- Bitwarden + Aegis (password manager + OTP)
- Eternity (for browsing lemmy)
- Mull (hardened firefox fork)
- Organic maps (maps + directions)
- Track & Graph (for tracking trends/habits)
- WebApps (running sandboxed websites)
Just begun exploring using:
- Immich (selfhosted photos solution)
- ReThink (local dns/firewall tracking blocker)
Btw, I believe Obsidian isn’t FOSS.
Been using it for a while, and am pretty happy with it. It has some nice features, and works pretty well for me, so I’d recommend giving it a try. I believe it, unfortunately, doesn’t support OVPN though. But as I understand Wireguard are to be preferred over OVPN anyways.
