Incorporate SimpleMDE or alike into the web application

It would make the text editor in the application much prettier.

Another idea is to wrap web application in an Electron app.

Hi @patarapolw, I like this idea! I've been meaning to come back to this project for a while but not really had the time. It'd be useful to draw up a list of improvements people would like to see, so I'll start with this!
