Stealth, Wraiths and Monsters

While searching arround the english.str files I found several interesting abilities (Including stealth, the ability to dock ships and several other ones)that I'm assuming must have been planned abilities for ships but were never finished. When creating a new component for a ship if you give it one of the abilities found in the strings file the ship does actually display the ability ingame.

So has anyone firstly noticed these strings before and secondly know if any of them atleast partially work? I know one of them (can't remember which of the top of my head though) doesn't actually appear correctly and caused some strange behaviour ingame.

Also my searching through the .str files dug up Gigantic and Unknown hulls through modding I managed to create a new Organic class hull which appears in game as a separate category of hull to the tiny and small ones. Once you research up to huge hulls this category disappears as there is only enough space for 6 classes of hull. So is there anyway to add in an extra row for these new classes of hull? I tried using desktopx but had very little success.
