Welcome Jeff and VerticalScope! Best wishes in your stewardship of the site. I am a longtime member and consider it my go-to discussion forum for airline and airport matters, and airliner-photo database. For instance, I check some new-issue 1:400 diecast airliner models against your photos for accuracy.
There are features from the "old" site that I would like to see returned.
--First, when one looks at a photo, it used to have an option to click on some code to have a thumbnail of the photo show up in a posting at another site. For instance, I discuss 1:400 airliner models at a couple of sites. I used to be able to post thumbnails of Airliners.net photos for reference in my postings, which was very helpful.
--Second, the search feature used to have an option to search by decade: 1970's, 1980's, 1990's, etc. It was helpful for my management of my 1:400 collection to be able to find out what an aircraft at a given carrier looked like in a given decade.
--Third, I second all those

who ask that the 'hover-over' feature for airport codes and airline IATA codes be returned.
Fourth, count me among those who strongly believe that the old-style blue look, is far superior to the awful white look and weird formatting of the first version of the "new" site.
Sincerely,
Jim
