Please do not rebind my keypad. I use that for all of my thrusters (And I usually use almost every key). The ablitiy to rig up more than 10 thruster keys would be nice if possible.
What I really think this mod needs is improvement on the prop protection system. I was impressed to find that chimneys are already restricted by default. The prop protection system though sometimes seems to give rights to the wrong player. Sometimes, griefers will phys gun your unclaimed props as well to make sure you can't use them or delete them without deleting all your props of that type.
A voting system to unlock a players props temporarily would also be useful, though kicking them off the server with the current votekick system and then deleting everything after the grace period expires would also work.
What I really want though is a way to deal with players who want to chimney spam. If they press the chimney button rapidly 3 times in succession for example, they freeze in place and catch fire or something and a big text message appears on my screen saying what they have done.
I have also noticed that sometimes people are able to weld to my protected props. However, I can't unweld these items from it as they are protected.
In my opinion, the anti spam and prop limiter systems along with prop protection are the key reasons for having this mod.
May I also suggest a no-spawn physical bubble of some sort? I usually build fragile things and players are still able to grief by dropping containers and other such things. A medium sized bubble where other players couldn't spawn props inside would be useful. This bubble would also act as a physical object to the outside, allowing work to continue inside it while anything dropped just hits the bubble. OF course, you would have to freeze it in place. I would limit it to one per player and make it unweldable so it couldn't become a griefing tool. Some method of protection is definitely in order though to prevent people from dropping stuff on your creations.
