My my, you have been busy. This is fantastic, it adds visibility of a number of steemit metrics that really should be present in the native GUI, like votes/voting power/actual vote value (how accurate is this? no offense intended)/mentions/wallet history...

The media gallery is a nice touch, and so is the integration of the markdown editor - I've been using HackMD and StackEdit for this, which editor does your plugin use, does it draw it in from github or is it embedded in the plugin code?

Any chance of the following?:
