This is a fantastic plugin - takes a little time to fully understand but once you do... wow!
I have a couple enhancement requests that I think would really enhance the product:
Allow cache purging of individual Pages like you can for Posts
** If you pull up a list of all the posts, you can hit a quick link to purge the post from the page cache - but that feature isn't in the Page functionality. This hopefully is an easy improvement!
Provide a cache summary page
** I have been going into FTP to check to see if my pages are cached (in quantity) and also to monitor caching when I do a purge and pre-fetch. It would be great to know how many pages are cached but even better if a full list of all URLs cached could be displayed with their cache data (date cached, last checked, expiration, etc?).
Again, fantastic tool... kudos!
