OnlyOffice is also available as a (offline) desktop office suite, so as a user it’s more like LibreOffice than Collabora.
My wife prefers OnlyOffice over LibreOffice, as it’s feels closer to MS Office. Also it’s compatibility with MS Office formats is better than LibreOffice.
I still use LibreOffice for desktop, but I’m not a heavy user. Haven’t tried out Collabora or hosted OnlyOffice for NextCloud yet.
The biggest problem with Discord is that its an information black hole. Its not properly searchable and not indexed by search engines.
Discord is fine for casual chat, but horrible when used for forum-type discussions and even worse when used for documentation.
You see the same problems being discussed and solved again and again, but you cant just “link” someone the solution like you could with a forum thread cause its spread out over 3-10 chat messages that are interleaved in-between other topics being discussed in the same room
Anything of long-term value for the project (forum-type discussions, documentation etc) should not recide in Discord
I made some notes while I had a problem with Zim flatpak not following Breeze GTK theme:
https://docs.flatpak.org/en/latest/desktop-integration.html#applying-themes //The applications will try to match the system theme currently being used, if it corresponds to any of the Flatpak themes installed, and will fall back to Adwaita (if they use Gtk2 or Gtk3) or the default Qt theme (if they use Qt) if a corresponding theme isn’t detected.//
== Solution: == ‘‘flatpak override --user --filesystem=xdg-config/gtk-3.0:ro’’

( I tried to install ‘‘org.gtk.Gtk3theme.Breeze-Dark/x86_64/3.22’’ but //“This theme has been replaced by org.gtk.Gtk3theme.Breeze, see README for workaround on using system color schemes. https://github.com/flathub/org.gtk.Gtk3theme.Breeze#workarounds”////////
