Leonard, go write some code that will make a purge tab show up at the top of the page There is, I believe, an extension that does this and also several other admin commands (for admins only of course). But knock it into shape and trim the fat.
Do we really need it all that frequently (honest question)? Clicking "edit" and then "save" (without changes) is only 2 clicks, do we need to modify the software to save 1 click?
