Hey there.

This editor is fantastic. I really wish I had known about it before writing my workshop addon description. Due to the lack of preview functionality in Steam, up to this point I have had to update my description and hope I've not made any mistakes in it.

One feature which would be really useful is the ability to copy & paste existing Steam markup into the editor. This way, I can paste my addon's existing description into the editor and make some changes to it.

Also, could you possibly add support for the [img]https://i.imgur.com/pgpeH1I.gifv[/img] image tags?
