this add the quicktags to the edit comment view. If you will use the buttons also on quickedit of comments add an small plugin, see in readme of the plugin or on this gist: https://gist.github.com/3076698 or use the plugin inside the plugin folder, but you must change the file name, kill the .eexample string for use the php-file.
Thanks for reply.
Tested and works perfectly! Thanks for taking the time!
Note for others: if you need this functionality as well, remove the .example part of addquicktag_quickedit_comment.php.example filename. The file is a stand alone helper plugin for Add Quicktag and you’ll need to activate this file (plugin) separately in ‘Manage Plugins’.
