After the skycrane deployed the curiosity rover; Why wasn't the sky crane launched into orbit as a satellite that could have been used for communications instead of crashing? Technology-wise; This would demonstrate the capability of launching off the mars surface. And provide a another use of the skycrane concept.

Suggestion for "the next time" we use this landing method. After releasing the rover, fly the descent stage platform to another location of interest (the top of Mt. Sharp?) and land it softly vs. crash it. It seems to be very capable of controlled flight within the atmosphere - and thanks to the team it seems very fuel efficient as well!! Seems a shame to just trash it. Put a 360 camera on it and some other instrumentation and make it it's own platform. GREAT JOB JPL!!
