The dial thing doesn't worry me too much. If they can pull off a slight of hand stunt like that, then like Corellian Corvette said, they could just nudge the actual dial to whatever they wanted on the pretext of 'aligning the command stack' or what not. If someone has a WAAC mentality that goes as far as cheating, then they'll find an opportunity. They've probably already worn out the plastic movement tool's 'clicks' anyway.
... that movement tool, while a cool idea on paper, is terribly uncomfortable to use when there are fighters and other ships cluttering the table, the tool very often forced people to remove their fighters for the sake of movement and then put them back where they were...
I never got how this was much of an issue. Not because I didn't trust anyone, but because I was fairly certain when I first opened the box, that the 'deployment zone' bits were right angles for marking ship that had to be removed for the movement tool. It turns out I was wrong, but they still work terrific for that purpose. Then the starfighters... well, It seemed like common sense to make a simple marker chit (or 4). As long as you can cutch a V notch in something other than your hand, then you can cut a triangle or square base with that V and the squadron base will fit into it. Facing doesn't matter, and the space will be marked.
Post Scriptum edit: Or you can do what Ninja Sensei Lyraeus said and buy a set like that. I don't have the patience to wait for shipping, but yeah, that!
Rules say you just guess rather than move anything if manouvering a ship.
