Golly, I hate to ask for something considering all of the recent enhancements, but I’ve got one for you to put on “the list” when you get time.
There’s not a convenient way to get to the FlightAware > Live Flight Tracker > Aircraft Type > search.
The only way I have found to search for all inflight of a particular type, is to go to the main live tracking page, click one of the pre-defined types, and then change the type to . With the new layout, seems like there is room to add a Aircraft Type query box over on the left after Airport Code queries.
When you get time!
