When we're you planning uk2000 EGLL customisation?
Well, it's already customized, but not at all parkings, I'll surely have a look at it (of course, you can do it quite easily with the scenery editor).
In any case, the other feature of yesterday's Live Update, which is support for multiple scenery .INI files, might not seem a big feature, but it was requested by UK2000 developers, since they are planning to release their upcoming sceneries with GSX support out of the box and they use multiple AFCAD configurations, so I guess they might prefer to do the customization themselves.
