It is supposed to, but its wording, to display "All" schematics with "Minimum skill required: " "Structure Expertise I". However, it seems it rather just shows the schematics which are awarded at that level, and not minimum.
Thinking yet another turn (could it be something in SWGAide coming up?
) I guess it makes sense to have 3 ways for this filter: maximum "skill", equal to "skill", and, minimum "skill". For a newbie the first makes sense. For a nerd the middle makes sense, hehe. But the last one, yeah, I wanted it this time, but there is no obvious use but more fussy situations, plus completeness of course
