Therein lies a huge problem. When I thought of an external editor/upload tool, my first thought was how to pull steemit's editor out, and then provide a path to pull it out again whenever it was seriously updated. But that makes the tool tied to steemit.

Thanks for sharing this core paradigm of your project.

For note: I think it was quite ... stupid for steemit to put in a class name into the base css, so that it will trickle down to posts. As in, it is impossible to find out such a detail if you come new to the project. And, it is so easy to break.
