What I’m trying to do
I’m trying to add a new language (Finnish) to the list in Editor → Behavior → Spellcheck languages, on Fedora 41.
Things I have tried
Installed: langpacks-fi (which installs for example libvoikko) + restarted Obsidian.
Installed: GitHub - antoKeinanen/obsidian-finnish-spellcheck (through the custom plugins). This seems to work a bit differently with a custom “Spellcheck” command (which did not appear for some reason, though).
Question
What steps are required to add a new language to the list? Could the obsidian-finnish-spellcheck or libvoikko be used somehow to add Finnish?
