Pinning
paz tries to keep the RDF store to a minimal size, by purging old unpinned content. You can also trigger a store cleanup by using the store broom from the left panel.
When a note is pinned, it cannot be removed by the store's garbage collector.
After pinning a note, you'll see a red pin icon on the note (hovering the icon will show a tooltip with the note's pinning expiry date).
