Yes and No. We pulled wordwrap because it doesn't work with line numbers, however, it does work without them. So we're going to add an ability to use wordwrap, but it will disable line-numbers. Go-to-line does work with both, so we should be good to go.
RokPad should work with ZOO, we've been reported by YooTheme about the issues and we collaborated to make the two work nicely together. This was a while ago though, Is there any new issue we are not aware of?
We periodically update RokPad when outstanding updates are in CodeMirror, we even provided fixes to the author of CodeMirror. For a while now we've been using a trunk version for RokPad as it was more stable than the current released version, so depending on the issues and the new features we update CodeMirror in RokPad.
My problem is that the editor area is stretched to the right[1], but its also hidden underneath. Making it a bit hard to work with. This is with ZOO 2.2.3 I think.
