Grid background color of Traditional Props

[Michelle]

Is it possible to change the grid background color of traditional props in S5?  I thought I could do this in previous version.  I know I can change the "on" light color by editing the prop definition, but I see no way to change the grid color.  The real issue is when using either the toggle button or the "on" and "off" buttons, my cursor becomes a tiny white line that becomes almost invisible against the light gray background.  I'm having some serious eye strain.  The RGB prop backgrounds are black and the cursor can easily be seen. 

If there is not way to change it I'm going to have to get some new glasses to support this hobby!  Overall, I love S5.  It's making sequencing so much easier!
