I have just stumbeld across your inquiry program and as a long time user of offline explorer pro (for the last 4 years I always used it for any kind of download I needed) I must say that inquiry has some things missing, that would be great to have:
command line interface to make saved snapshots of page by just using a command line command (could be used in combination with a scheduler)
export the page to a full size image (like bmp, jpg etc.) to make it easy to forward this kind of page snapshot to someone else
auto creation of webpage specific folders based on the webpage being a snapshot is made of
make it possible to save/load keyword lists for search pages
make it possible to only search the most recent downloaded versions of all pages
These are just some things I noticed missing right away after playing with it for a couple of minutes.
I`d be happy to provide you with more ideas to make this a real nice application.
