Firstly, long time user, and big fan. Absolutely love it. Prior to your excellent site weather forecasting was a best guess, now with windyty it is remarkably accurate here in South East Asia.
I would like to suggest that you extend the route search capability to support multiple points, i.e. VTSP VTBD VTCC three airport points or more delineated by space as you do now.
It would extend the route planning usefulness for aircraft by mirroring actual routes flown which are seldom departure to destination but made up of various point to point segments.
Thanks for the consideration.
