Thanks for the great editor, guys!
A little usability-related feature request: I think it would be convenient if a right click on the weapon slot (or any other slot) would bring up a dropdown menu with items already used on the same slot for other units in the mission.
For instance, if I gave an AK-74 to a Soldier1 and, after editing some other equipment, switched to Soldier2, a right click on the primary weapon slot would open a dropdown menu with "AK-74" already on it, so that I don't have to go through all the lists again.
Similarly, applying unit profiles could be made more efficient by turnig the "Apply profile" menu item into a submenu containing a preloaded list of all profile files in the "Profiles" folder (maybe including subfolders). Thus a profile could be applied in just two clicks instead of going through a "Browse" window.
