Hi Weter,
I appreciate your feedback, and will look into making platforms stand out more. By the way, do you like the dashed path, or would you prefer it to be drawn as a solid line as in the old Map window?
"Allow new players to join" controls whether players who aren't in the multiplayer server may join the session. If it's checked (it is by default), people will be able to join your multiplayer session normally. If it's unchecked, the server will refuse any new connections and those who attempt to join will start in the classic offline single player mode instead.
I copied "Penalty for speeding & SPAD" (the double ampersand && is necessary as explained
here, but I should probably change it to the second solution to avoid confusion) from the old Map window. However, I've just done some digging into the code and it appears that this option actually
does nothing. Essentially, in its current state, it's a waste of CPU time. It would be interesting to hear from a developer who knows more about why this option was added and if it is still needed or not.
