[MMO] Post Edit Reason [Free Add-ons]

I am trying to change the location of the edit reason notice within the post. I would like to place the reason behind or beneath the edit date and time. Can that be done somewhere in the templates? In the templates of the addon I could only find the one that adds the form field to enter the reason in when editing.
BTW I like the way the action bar has icons without the text only appearing on hover like a LESS-modifikation did, that I implemented. Is that an addon, or simply CSS?
