Great list of apps. The only few things I could recommend on top of yours are:
- tasks.org for tasks (and it can easily replace your calendar). It’s foss, and has good syncing / backups.
- You could move off aegis and put all your 2fa in keepassdx. It supports 2fa already, and has smart form filling for it too.
- Readera for ebook reading. Not FOSS, but its light and works really well.
If this is for torrents, the binhex qbittorrent docker can do this for wireguard.
