Having the appropriate rotate, best glide speed, pattern, over the numbers and touchdown speed, and VNE at a glance would be nice.
A pop-up warning for approach to stall speed and VNE would be a great safety feature. If someone were to get "heads down" in the iFly and loose situational awareness, a pop-up might save an accident, or at least an embarrassing situation For those of us who fly multiple aircraft, having each aircraft's appropriate V-numbers available quickly would be a nice feature.
A pop up menu at boot asking which stored aircraft is being flown (tail number?) could load checklists, flight planning parameters, and V-speed information.
Having the correct checklists and speeds available from a single on-screen menu would be a great safety and convenience feature.
