Hi Bogdan
The issue of DSO displays has been around for some time.
The initial work was done about version 0.7.1 I think when Fabien was first working on the DSS display.
There was an extra button on a prototype GUI F4 menu in version 0.10.? that allowed the selection of image sources (visible/invisible)
This was used in the virgo version and I think maybe in Fabien's Toast-images branch. 
I imagine the code is already embedded somewhere in the core.
Is this what you are driving at?
