Very exciting and much needed improvements! Especially the new design and interface, as well as the experience and ranking features and, of course, referrals. You could also consider adding an achievements system (like "mini-Steemitboard": mined X SBD, gained Y experience, referred Z friends, etc.).
As for the community aspect, it would be nice to have some sort of in-built messaging to replace communication via Discord.
I am certain that Steemeum IS ALREADY the best mobile mining app and I appreciate your efforts to make it even better.
