I'm not quite sure if this goes under OXCE or Xpiratez per se, but here goes:
One annoyance is that the screen where you especially would want it, the manufacturing screen, there's no way to view specs of the item in question. CTRL-m-click and m-click both take you to the tech browser, so you can't compare relative merits of, say, DOOM armour and Legion Armour before making some. Yes, you can go look it up in boobiepedia but to do that you have to back up to the geoscape.
I have no idea if this is something not easily done because of Star Gods but it's something I futilely reach for quite often.
