Excellent suggestions as always Didi. I'm not altogether sure if we can deliver trend info like you suggest/want, but I'll have a look at the backend DB and see what's available.
Do we not already have a pilots by country (where pilots tell us) function? That should be relatively easy to do, leave it with me for a week or two (as Callum has suggested, there are a few other things underway at present that are using me free time... but it'll be worth the wait, I promise...)
