What I'd like to see...
Supercruise exit to planet being the point at which the transition happens, so you exit at the point where SC would normally kick you out of ftl but instead of an emergency stop you keep going.
Mining machines like the MB-4
Some way of protecting any persistent assets you might have on a planet
Planetside starports like in Frontier and FFE
Expensive atmospheric shielding for big cargo ships
Gravity and drag
No making it too easy because people whine about trying to land a thousand tonne metal brick on a planetary body.
I'll add: Identification and cataloguing of new species, both plants and animals. Archaeological, um, things. The ability to trade with native species for rare items, possibly establish reputation and business contacts. Repopulating new plants with new species.
