I just mapped my first ELW that I discovered a while ago, 29 to go (with new ones hopefully).
Scanning systems is so quick now, only mapping takes much more time than a full system scan pre-3.3.
Thanks for the link, I'm looking forward to trying it out. Yeah I much prefer the new scanning method. It's an enjoyable minigame that breaks up the tedium of exploration.
