Unfortunate.
But this made me wonder: would it be easy to implement a similar "hiding" mechanism (mouse right click to toggle) in the equip screen that already exists in Buy or Manufacture screens? This would also make equipping more straightforward as you could hide the junk you almost never will want. I suppose it shouldn't be too difficult. Then the loadout could be modified so that it doesn't automatically add those items you hidden, you have to do it manually (or remove the hiding).
Maybe this should be posted or moved to as a separate suggestion.
