"Dark slide" for digibacks
Yes, of course. Forgot about that! I'll see if I can figure out something for my Sinars.

Is the sensor not protected when slid out of the way for focussing?
With wide angles, there is not any spare distance for a sliding cover, but with a Sinar you get the slot where you inserted the ground glass and then the film holder...
Given sufficient room, (depending on bellows and lens) it would be simple to incorporate a slide into the adaptor or the sliding back.
You could leave the back attached to the lensboard and adaptor, and use a standard frame holder (which has two slots, one for the bellows and one for the lensboard) an use a standard blank (no hole) lensboard as a slide.
... or you could make a non-standard triple slot lens-board/frame holder and use the middle slot for a protective slide.
This would all be less bulky with a Sinar P3.
