You know you can still do that with the FSS? Instead of scanning using the FSS interface, you can in fact fly close to system bodies and the FSS will passively scan them. The only difference being - which I know will be pointed out (

) - is that you will be playing the parallax game in order to find the bodies. Actually, some folks have been wishing for that for a long time now (the parallax thing) so for some this should technically be a good thing for them.
I'm converted to the new system. I've gotten to the stage that just by looking at the FSS radio frequency thingy at the bottom I can judge whether it's worthwhile staying and further scanning or not - kind of like the old ADS/instant system map. Not as in-yer-face quick as the old ADS/system map for sure, but there is something about being able to judge using the FSS spectrum thingy which to me adds a bit more "skill & judgment call" to the game which I'm finding adds more enjoyment to exploration. YMMV,This is my subjective
opinion only, yours may be different. E&OE etc.
