[U]sable item hint.

[AssumedPseudonym]

 Not a major one, here, but one that might be worth mentioning. This is one that’s only going to happen at the beginning of a game before you have used any items, of course. If you have an uninstalled device in your cargo hold that you can only be invoked when it’s installed, the hint still pops up even if you don’t have any other usable items. Pressing results in the “No usable items” message.
 Anyone who’s just learning the game and might actually need the hint probably isn’t going to have a mod that would put any such device into their cargo hold at the start of the game, but still.
