Sometime I do have 2 monitors with different resolutions ..
And as dai sometimes I do enlarge IA manualy to cover almost both in order to apply the tools without blocking the image.... 
Somewhere I have read that some programs do use one mointor for browsing (thumbnails) and the other one for the main image....
But IA does not have the need of that kind of funtion ( at least I do not need to have it those files open all the time) ...
So the idea of multimonitors in full screen would be something like one for the tools and other for the image ...
With the increased space available perhaps it would be possible to make the "color map" controls scalable ?
Just another idea ?
