When I click the button line for insert the line (HR) into text, if the cursor isn't to start row of the text doesn't work but show the ---- between the text.
I fix this little problem change the toolbar.php file:
'type' => 'insert',
'title' => $lang['qb_hr'],
'icon' => 'hr.png',
'insert' => '\n ----\n', //MMM FIX
I have insert a \n for force the ----- to insert at the start row
PS: into the attach file I have add two new button: "new line" and "box code"
PS: sorry for my bad english
