/u/Humanistix : I'm late by reddit standards (2 days old already yikes), but we're actually planning on adding this. It'll be slightly different than what you suggested since we also have to consider mobile, but you'll definitely be getting this info.
We're actually doing a bunch of updates to this screen, so to minimize confusion we're bundling all of our improvements to the reward screen as one package. That means it may take a bit longer to arrive than our updates to other screens (like deckbuilder), but we're not going to leave the reward screen as is by any means.
