the new update has to have SMP support because of the way minecraft 1.3 is set up.
the GUI control extension for this mod is for the controls window under the options in the minecraft pause screen. without it the done button is in the way of the control settings of the zeppelin, things like, forward, backward, up and down. chaining to other blocks applies to the nonfollow blocks in this mod. for example GNS uses note blocks to line the bottom of his ship so he can land it anywhere and not have to worry about his ship including his landing pad or the ground.
Asikar is correct, 'not chaining to other blocks' means just that - it won't link to other blocks. It is helpful to think of it this way:
When you turn the controller block on, it reaches out in all directions (except diagonal, by default) to link blocks to itself, stopping only when it runs out of blocks to detect, or if the size limit is reached. This linking obviously goes 'through' blocks, like a magnetic force. A no follow block can be linked, but the linking will stop at that block and go no further. Line the underside of your ships with this block.
This allows you to land your airship on virtually any other block, even other no follow blocks, and you can freely turn your airship on and off without fear of it linking to the floor/ground by mistake. You can even put these blocks lining the side of your ship, so you can moor the ship against a midair walkway (in case you have ships that were never designed to be landed directly on the ground due to their size or to belly turrets, etc).
