I would like to see a way to clear checklist items that the aircraft cannot detect are done (like 'Tower .... Notify'). This can remove some clutter on the display, as in some checklist a few items are left, and can make it hard to see where you were.
And maybe a way to 'scroll' up and down in the checklist, instead of the weird thing we do now using the CLR key. Same to scroll the Status if req'rd.
