Display Hotspot

With the Hotspot question type- the pre-defined options are framed grey (Screenshot 1_hs) 

So far it was a transparent box (better readability if you use a text picture) (Screenshot 2_hs) and when it was selected it was slightly grey but still better readable. (Screenshot 3_hs)

Is ist possible to change the colour or make the opacity adjustable?

 To do

• the color of the frame can be chosen
• the shading of the hotspots can be either turned on or off
