Not a huge electron fan (thank god for tauri), but Obsidian is a fantastic app and you shouldn't let the electron put you off of it. You can even hook a MCP up to it and an agent can use it as a personal knowledge base, it's quite handy.
I think I would prefer to see official supports for major package managers, even with unofficial repos (Debian, Macports,...). We went from a time where software were usually tarballed to one where devs are encouraging piping to shell.
