Narrative:
During taxi out; leading edge flap/slat #7 was malfunctioning. Given ramp constraints at sna; we ended up clearing across runway 19R and dealing with MEL. During course of MEL compliance; not all steps were completed. Maintenance/dispatch could read or verify compliance with MEL; particularly the non-flying portion of the documentation which may not be as familiar to the pilots. Further; the color coding in the opc does not lead the eye to all of the mandatory completion items using color. It does highlight them; but given the small screen; color coding with links could be helpful; particularly for the clean-up areas.
