Two candidates for my best-discovery-of-the-year prize,

Ptyxis terminal: https://gitlab.gnome.org/chergert/ptyxis A modern take at a terminal, gtk-4 native, gpu accelerated, container-aware etc that replaced tilix in my setup. And it comes neatly packaged as a flatpak

LogSeq notes: https://github.com/logseq/logseq A different approach to note taking & journal. Very nice looking, rich plugin ecosystem, could use some performance boost but I think they are working on it

Big shootout to flatpak/flathub that for me has finally taken off, I converted all of my regular desktop apps to flatpaks. Went from 3-4 apps last year to ~20 (including Firefox libreoffice, even my terminal app) this year and not looking back. This has made doing a major host SW upgrade almost painless for the first time in 25+ years using Linux desktops.

I concur with the first comment, RPi is not well suited for a media server, where you need solid storage and good performance for transcoding on the fly. However, RPis are fantastic media players

Did you check logseq? It’s on flathub
