I don’t know about you but I would like to know if a system has the interference index up, particularly for hunting purposes and to know which systems I can safely ignore on my search to launch one of them to crab. Ideally without having to carry one of them around like a canary in the coalmine. For all I care, they can turn it into one of these collapsible HUD elements that you can hide into the tiny icon above the system information. But after this horrendous window focus update a few weeks ago, it should not require you to use the map that extensively to figure out information which should be easily visible at a glance without extra menus.
However, what’s good is that there is a map filter for both maps(!) for the SIS. That is very much appreciated.
