As a SD user I would find it useful if there was a way of creating a customisable checklist for my aircraft so I dont have to switch between apps or use split screen modes.

Two of the aircraft I fly have very good electronic checklist on the G1000 and IFD440 fitted in the panel. Even having gone to some effort to set them up correctly, no-one uses them as everyone tries them once then goes back to the paper version which are easier to use than an electronic checklist.

Perhaps. I suppose though that SD is on a tablet so the form factor is different though.
