It hit me right after that last update that pinned notes should persist across refreshes (we're building here, after all), so now they do. You'll need to refresh the page to get the update, but now your pinned note in NostrGram will remain even if you refresh the page. That way you don't have to go hunting for the note again. It won't restore the video/audio to its previous location, but at least you won't have to search for the note! Very useful for rejoining Nests also.
