I think folks have touched on this, but it would be nice to see the coins broken into the algo category, both for choosing as payment, but really for this scenario, I'm running my S9s here and do not need to know which scrypt blocks are found. I don't consider this a big issue or priority, however, I do think since you are collecting all this data that maybe it is not to hard to separate and collate
Another user suggested being able to move the boxes or resize them, I think this would be a nice feature too, or at least the ability to minimize them.
Nothing pressing, get them 40 exchanges working with you
