So there's a new MSIE web developer toolbar out-and-about. Like the last version, there's a lot of good stuff in there. It's not Firebug, but nothing else is. Anyway, it does lots of stuff you want, in particular, it replicates the fast-path for cache clearing that the Mozilla Web Developer Toolbar (that the MSIE one is a clone of) provides and goes it one better by promoting it to a top-level button.
And then it gives you a confirmation dialog. I shit you not.
Removing one click: good.
Leaving another (useless and impossible to disable) click in the web-dev fast path for a non-destructive operation (it's just a cache after all): stupid.
