As one of those people that uses Obsidian without plugins, what plugins do you consider essential?

I rely on Advanced URI, which opens certain functionality up to external apps. I use Raycast and with Cmd+Space, it lets me open vaults or daily notes. And Obsidian_to_Anki, but that's probably just me because I have no clue how to use Anki otherwise.

Me too.

All I want is a top-notch Markdown editor with a mobile app and trustworthy sync, and that's what Obsidian gives me. And if ever Obsidian goes away or is enshittified, I'll still have a perfectly good folder of Markdown documents that I can take elsewhere.

Same here, zero plugins for me.
