I've already asked him to add a same-day-roundtrip option to the month-long search feature. I've also asked him for a lowest-fare-to-anywhere search, with an option to specify the minimum distance. He replied that these were on the ITA to-do list, but he would not provide a timeframe for completion.
I willl pass on further requests, but let's first come up with a priority list.
As for your particular requests, you might be interested in CoMETS, the cross platform standalone database application that I've been developing. It's approaching beta release; for a preview, I've posted some
screen shots. If you have feature requests for CoMETS, this would be a great time to let me know. Please also let me know if you'd be interested in beta testing CoMETS.

CoMETS update (18 Feb 2005): CoMETS Beta 1 is now available for both Mac OS X (password: ftcomets) and for Windows (no password required). When I find a little time, I will post a short movie demonstrating CoMETS' functionality and ease of use. When I find a little more time, I will release Beta 2. FWIW, I've been using Beta 1 for several months on my PowerBook and it has been rock-solid.
UPDATE: The
CoMETS Movie is finally here. Check it out to see how CoMETS will give you maximum info for minimum effort.
