Thanks to a great idea in a post somewhere by Derakon, here's a mod that applies the highest level armor repair item in your hold to the most damaged segment of armor on your ship. Select "Emergency Armor Repair" in the Ship's Interior dockscreen.
Patches, kits, paste and nanos can be applied. Doesn't work with Sung tiles and doesn't recognize unknown barrels.
I might make it into an item that you need to buy for balance.
I could probably add the Sung tile thingy but I don't know if anyone ever uses Sung armor.
