Earning history (under mining in summary) shows earnings from mining AND earnings from offerwalls. Offerwalls should have a separate earning history, as do referrals, for consistency and unambiguity! 
A major concern I have with how it is now, is users seeing a large spike in earnings (from offerwall earnings,) and not being able to see the graph clearly. Attached below is that issue.
This would be great, I remember someone recommending this in the Salad discord server a while back whenever the new UI was originally implemented but I guess the idea sort of died out. Color coding each income source (Like green for mining, blue for offerwalls, red for referrals) when not filtered would also be an interesting addition.
I made concept art for this back in July:
That’s the picture I was thinking of, it’s a pretty neat concept.
