1. Make a place for the registration and airworthiness cert that is visibile to pax, so it complies with the FAR.

2. Make the new fabric "chart holder thing" between the seats wide enough to actually hold charts.

3. Build a pocket into the back of the seat - easy to stash water bottles etc. down there.

Cubbyholes below your knees are great. Map pockets under the panel are good, but make sure that they don't get overly full, or stuff comes out during climb.
