This is a great request, however we need to keep in mind how difficult this might be to achieve for the developers.
I personally have a big need to be able to interact with .org files since I take a lot of notes in org-mode.
Perhaps try to list the specific types of files that you think would be a top priority for you.
Obsidian a notes program
I also use a lot of different type files, but it’s important to keep in mind that Obsidian is a note-taker rather than a full text editor.
Obsidian is significantly different from apps like to VSCode, Sublime, Emacs etc. Right now it’s pretty much a powerful markdown editor.
Extending file support for the purpose of note-taking / PKM
Like I said I still see the value in this request, but I would like it to other notetaking file types, since that is within the sphere of what Obsidian is.
With that said I’d be the happiest person if Obsidian fully supported .org files for org-mode, but I might have to do a separate feature request for that.
