We're open to suggestions!
Please note X-Plane has a 'rheostat' dataref. It is designed to add integral and panel lighting level control to the cockpit in a standard way. With XP11/10, there can be multiple rheostats in the panel, like you'd find in the stock Baron 58 for example under the right seat yoke, and these are each an index in the dataref values array.
My post above about the helicopter shows that some aircraft modellers decided to re-use this dataref for other purposes, in that case, driving the light level of a strobe light... This is not what these datarefs are meant for, or at least, I'd expect modellers tweaking the system for animation purposes would leave alone the first 4 dataref indices.
Our plugin offers the setting to permit you tailoring the source to the light, i.e. to connect which rheostat drives which light sources in the GNS (keys and screen). This is designed so that it gives the maximum flexibility with third party aircraft not following the stock standards.
It seems easy enough (for an aircraft modeller) to add a standard X-Plane rheostat to drive instrument lights that you might want to 'pressure' the aircraft modeller/vendor to do it.
This discussion gives me the idea to take provision for a '-1' value which would disconnect the screen and/or the keys from any rheostat in case there is none in the panel. To add in the next update!
One last question, where in the filing system are "user way points" stored??
I want to load about 100 of them from my real GNS530 but would rather not do it by hand.
These are stored in the device non volatile memory. This is not extractable as such, but can be cross-filled between units (and you can make a backup of the file on your hard drive in case it becomes corrupted).
Please note we have been looking into ways to offer a user waypoint import (and maybe export) function to the product, but we didn't want to delay releasing the product for the vast majority of users. Another 'to do' in the list for next updates!
