Codemirror in RC3, awesome! Would like to use it as a resource editor as well...

RC3 is fantastic, and the addition of codemirror is a dream come true and has simplified my workflow.

Now I’m trying to figure out how to make it work as the general RTE, too, since I prefer to just write the html when creating content to using a full-blown editor like TinyMCE. Is this possible with the new module?

Not at this time, but it could be added. Could you add a feature request here:

Agreed... CodeMirror is a fantastic add-on! This will make editing elements so much nicer. Great work!
