[FIXED] Gate Leasing Menu is...painful

[POTKC]

I fully agree with POTKC, the gate leasing menu is a little clunky and slow to manipulate correctly. Possibly could we even just refer to the CA method, listing by continent, then country, then city? (and you just lick on each category until you find the right airport?)

I seem to remember CA having a box to type the IATA code into, was that a thing or am I imagining it?
