Annoying representation of similar Items can get confusing (both in searches and for gearing/manufacturing tasks).. as indicated by the Arrows in this sample.
Odin & Mjolnir (with poisonous-green symbol instead?) ... Two (Motion or Visual Sensor?) Helmet Modules ... better to have distinct GFX for each even if we can trust tooltips should already give their ID). Maybe there's some more! Please fix, asap. ;)
