This would be super useful for us, though I'd sort of like to add an option to do it automatically on "~~~~" being entered. Enabling it might be a good first start, I can do the pull request and submit a new bug to update it when it's merged.
Version: unspecified
Severity: enhancement
That seems like an unmaintained (last commit 1,5 years ago, 20 commits total) etherpad plugin. We have no plugins installed in our installation and for good reason. Whenever we evaluated any of them, they invariantly turned out to either not be installable or where of very low quality and crashed etherpad. Closing as declined, sorry :-(
