I've thought about looking into pop-up dialogues for 2d instruments and animating 3d instruments into a more readable position but both of these would require triggering events. If it were possible to change the mouse cursor as it passed over a hot-spot it could also trigger the pop-ups or animations. Haven't actually tried anything yet, of course...

You could use the same XML code to make an instrument appear "unzoomed" or
"zoomed".
Thanks David, I was hoping to find something like that - my next
question would be whether I can parameterize the process of changing
the dimensions of an abitrary instrument/panel by using a corresponding
Nasal function - so that I don't need to manually implement the
resizing functionality, but could rather simply provide a nasal function
with the property path to the instrument that is supposed to be
(temporarily) resized.
The function itself wouldn't be the problem, rather I wonder whether
each instrument's properties (dimensions, position etc.) are also
made available globally within the property tree so that I could
theoretically modify them using something like:
setprop("/instrument/gauge/width","100");
setprop("/instrument/gauge/height","100");
So that I would ultimately only need to put this into a
wrapper function that I can then call using the action
tag.
Also, is it (currently) possible to deal with "mouseover"-events
using the XML files ?
