Ah, background images with hotspots....mmm...that might be quite cool in terms of ease of use of creating "ambience" with backgrounds, button placement etc.
I think one prerequisite for a 'hotspot' function though, would be for the hotspot to have a "rollover"/image2 image 'on_click'....in this way the bg image could have the "base" buttons and clicking the hotspot could load the 'on'/'rollover' image (like we use to indicate AP mode active, or electrical power on etc etc).
I tell you, the best thing in the world would be if the sim could "report" back to TB whether something was 'active' or not, then no matter how something was activated or not, TB could show the correct 'status' (i.e. AP modes and things like that).
One of the mods I need to do to my profile, now we have the latest release, is to change the AP buttons from 'toggle' to a 'hold' with noreset=1....cos then the macro_select could activate the AP mode and macro-deselect could actively disengage AP (i.e. Alt-9 in LOMAC I think)...whereas atm you need a seperate button to disengage AP (which I have mapped to my HOTAS anyways but..)
Hmm, so many ideas, not enough time to do them (still trying to play GRAW, fly the 504 flights and hold down a demanding job
).
