The following post is made to explain some features that I added on my previous developpement. One major UI change to display a more clearer information. Plus, I have added a comparaison between the two reward option (50/50 - 100%) value of a reward. The goad is to help Steemians to choose the best reward option based Steem and Steem dollar price.
A new interface
Because the previous interface was not very useful to compare the real value (in USD) of a publication, I modified it in order to have a more readable information.

Previous interface

New Interface
Market and feed price have been preserved but details of the calculations has been hidden.
You can displayed it by clicking on the "?" icon

New features
Because displaying the USD doesn't tell what is the best option to have more Steem Power, I have added an addition result to compare the reward in Steem.
For 50/50 option, the result is the sum of 50% SBD reward (internal market based) and 50% SBD reward (median price based).
For 100% Steem Power, the result is based on median price base.
Internal market and median prices are fetch from RPC full node (by default api.steemit.com)
SBD price is fetch coinmarketcap.
Some other features
RPC full node can be configured by modifying the following variable on top of the index.html.
steemApi_endpoint = "https://api.steemit.com";
If coinmarketcap or RPC full node cannot be contacted, the script fails and displayed a popup.

Last note
Obviously, this app can be used anywhere locally (without host it on a server).
