Quick question (apologies if it's already answered elsewhere, but I couldn't find it....)
For some airfields (E.g. Nottingham) if I zoom in on the chart I get a detailed airfield plate, but for others (e.g. Caernarfon) it's just the runways (and unless I imagined it, the chart zoomed in automatically when I landed at Nottingham, which was nice).  What's the rationale for which airfields have which?  From what I can tell, through the custom data creator I can only create the basic version.

You assume correctly, though you're welcome to suggest one for us to map if you like!

Nowhere in particular - it was more just a case of curiosity. I guess you have some sort of analytics in SkyDemon so know which places are visited most often?
For places like Llanbedr it would be quite useful, as there is no AIP plate and it's not immediately obvious which bits of tarmac are tracks vs taxiways. About half the places I fly into are unlicenced, and I'm still using a folder full of paper print outs of the airfield layout and key details like parking, club house location, etc - from various sources of varying quality .... can't help thinking there's got to be a neater paperless solution. I've got a vector (SVG) map of my own home airfield (EGNU) if that's any use to you (no use to me as I know my way around it just fine!).  
I guess the problem with you building them into the product is not creating these initially, but keeping them up to date, when significant changes happen like taxiway closures, or even simply the renumbering of holding points.
