ianonymous3000 great list, here's my feedback:
- The developer of Syncthing recently announced that development will no longer be continued. I'd remove it from the list as it will become insecure over time.
- For music streaming I'd recommend InnerTune over RiMusic as it's nicer to navigate and follows Material Design.
- For YouTube Clients I'm missing LibreTube as the easiest to navigate frontend experience (I'm personally using GrayJay and Tubular, but my beginner peers prefer LibreTube for its design and ease of use).
- I'd probably remove Zcash (and consequently Zashi) as it's not a "privacy by default" coin and harder to set up in a private way compared to Monero. It's also far less adopted by private services such as Mullvad.
That's all. Thanks for your work and research!
