Thread:Project:Support desk/Change the content / appearance of the revision line/reply (4)

I've done a bit of digging around, and it looks like there's a hook called UserToolLinksEdit that you can create an extension for.

Of course, you have to take the time to create an extention for this, and I don't know if this hook allows you to remove an item from the revision line; modifying common.css is much easier :-)
