Caches a site and never changes again. You have to start using "?clear_cache=true", "?now=force", "?ver=999", etc. to see if anything changes, and eventually THAT gets cached and never changes. Deleting the cache, data, and uninstalling and reinstalling the app doesn't help.

Simple! Really nice high-level overview of any site. Yes, it makes some assumptions and no, you don't have to follow all its recommendations - they're a general guide rather than a carefully optimised solution - but for what it sets out to do, this app is absolutely fantastic. Love it.
