Thanks for responding.
I think I’d favor keeping these notes into a different vault if it were possible to allow for links to notes in other vaults. That way, I probably don’t gotta worry about to possibility of Obsidian slowing up on me: Noticeable drop in performance of editor when file explorer displays over 1,000 items (ik this one is old and the OP acknowledged an improvement with Obsidian since posting it, but it still speaks to the idea of how much Obsidian can take).
