I posted this in a thread in the Dangerous Discussions forum, upon rereading it it struck me as worth submitting as a formal suggestion for consideration and review
I find it saddening that season two which was meant to be planets is drawing to an end and as of the close of beta for 2.4, the final bug update to Horizons, planetary POI is still very much a lame place holder and planetary navigation tools are non existant.
IMHO the exploration cartography scanners should pick up all the POI's in a system. If I had my way we would have orrery system map, a honk of the Advanced Discovery Scanner would pick up and tag all the USS's in that system (USS#001, USS#02, Etc...) which you could then target and scan to get more of a clue what is in that instance, ie is it a distress call, a convoy beacon, degraded emissions from a cargo drop, a fight (weapons fire detected) etc.
On planets surfaces I'd make the Detailed Surface Scan flag up all the POI's on that planets surface and tag them as Atypical Sensor Readings (ASR#1, ASR#2, ASR#3 etc). Then I'd have a mechanic in the system map / planet view where the ASR's would be marked on the planets surface in much the same way as star ports currently are. The new mechanic would would allow the player to select an ASR, select from a menu such choices as set as destination, bookmark, more detailed analysis. Upon selecting the more detailed analysis option the player would be moved into a new interface which would look vaguely like an advanced graphics manipulation program, and by means of manipulating some elements, sliders/knobs/values pull down selection of tools/software/spectrum segments to analyse they could deobfuscate the ASR, and know what is there and be able to navigate to it as a destination.
So much better than jumping in planetary cruise and looking for blue circles.
