Devwiki:Purgebutton This might do the trick? (Though it's personal use only)

Devwiki:DisplayClock This one can be installed globally and clicking it purges the cache too, however, it screws around with mobile editing (iOS at least, personal experience) so you can't bring up the copy/paste options.
