Not the big addition If you would want that the opportunity of an insert of a code was in "Quick Reply" that:
In showthread_quickreply Find:

<td><div class="imagebutton" id="{$editorid}_cmd_wrap0_quote"><img src="$stylevar[imgdir_editor]/quote.gif" width="21" height="20" alt="$vbphrase[wrap_quote_tags]" /></div></td>

and after that add

<td><img src="$stylevar[imgdir_editor]/separator.gif" width="6" height="20" alt="" /></td>
<td><div class="imagebutton" id="{$editorid}_cmd_wrap0_lj"><img src="$stylevar[imgdir_editor]/ljuser.gif" width="17" height="17" alt="" /></div></td>

And if want, can do too most with a pattern quik editing messages (postbit_quickedit)
