I have a feature request that might be difficult or easy, popular or only-Rick-wants-it. I don't know.
Often I want to look up acorns that I gave to other members' posts, for example if I don't remember which post it was that they are thanking me for. As far as I know, there is no way to make a list of "all acorns" or "all thumbs" I gave in a certain date-range or forum.
It would require searching for posts where Member X (me) gave an acorn to Member Y, maybe with a date range like "last week" or "last month". The date range would ideally apply to when I gave the acorn, but could instead be the date of the post.
If I was adding a filter like "search only certain forums", it would usually be my whole list of "Favorite" forums.
I wouldn't give that feature a high priority, or even a medium priority, unless lots of other people wanted it.
If it existed, I would use it to browse for posts in forums I didn't usually follow, like "acorns given by Member Z in Forum F in the last year".
