Yes, especially user interface, very well said.
Flexibility.. hmm I've just spend enough long time trying to transfer some STEEM to STEED DOLLARS inside my account and I gave up at the end. I wanted to promote this article and bought some STEEM and then I saw that I can promote it only using STEEM DOLLARS. I never understood why! It kinda reminded me when in 90's I had to shut down windows 3.0 in order to run another application in DOS. Shouldn't things be more easily nowadays?
