This is minor compared to some requests. But, on the portfolio page, consider adding sorting by both Floor Price and Top Offer. The existing sort by Purchase Price is "OK", but I think these two additions would be at least as valuable, if not more.

You can sort by top offer and percent below floor in the offers manager "Received" tab, so that would handle that part of your request. Sorting by floor price within your own portfolio i personally don't see a ton of value in as I think floor price is deceiving and the offers menu provides more actual insight.

The "Received" tab doesn't let you filter by rarity tier; card year; etc. I currently have 549 received offers. I don't want to scroll through all of them. Agree floor price can be deceiving. Especially when you get to the Elite+ level. But I still think it can be very informative at the core and rare levels. It's amazing how many people won't bother to make an offer, even though people have been buying for less than floor, and just buy at the floor as a default.

It lets you filter on PC but not on mobile for some reason - that is a pretty glaring issue with the offers manager I've noticed.
