Another WYSIWYG editor

I have an editor that's half done from a previous project (part of a demo), and I'm thinking to just finish it up in the next few weeks and put it out as another project under my belt.

It's not intended to compete head-on with established editors, it's just a side project I had wanted to wrap up and I'm thinking if more people uses it we can get it tested further and maybe it will be useful for everyone.

While I was researching I found a handful of editors, and their demos just shows the editor only (albeit with everything working inside). I had wanted some nifty tool that I can bookmark (like jsonlint), and for whatever I typed I can get the HTML version or the escaped version of it on the side so that I can copy and paste in my codes and move on.

So, very baby steps. My idea for now is just to have a single page, with the editor on the left, and panels of result on the right. Whatever you type, you can see different versions updating and you can click "Copy to Clipboard". A tool that you can bookmark and keep coming back to.

Does this sound useful to anyone? Will appreciate votes or comments. Thanks!
