It would be nice to be able to favorite (heart) a giveable item from the item's page so that it appears at the top of the favorite list when sending items to players' mailboxes. This would be separate from locksmith favorites and townsfolk liked/loved items.
I imagine the flow to be like this:
1. See a post in giveaways or trade
2. Click on the item link
3. Favorite the item
4. Go to player mailbox and see the favorited item at the top of the list
5. Aggressive kindness ensues
