This looks really good,

I would add a rewards distribution bar for distribiting rewards between SP and SBD. Currently it is confusing where you set your rewards distribution, and this would be a good screen for it.

I would suggest implementing an embedded Shapeshift function and bitcoin/litecoin/dash/ethereum/ripple. This would require some additional code, but it would open up an easier conversion to Steem. The negative of this would encourage rapid movement of liquidity from the steem account, but Steem is already protected against this by its use of Steem power and the power down function, so this would only encourage people to use their Steem account more.
