When I made the move from PC to Mac - I found the floating pallets was the single most frustrating aspect of Mac experience. No matter how much I try, windows end up shifting around, because my working window slips behind the pallets, obscuring needed Exit Group or tool specific buttons. Not having tools in the same place every time slows me down - even a moment of having to find the tool I need drags down the process. I see other people in the office with palets everywhere all over their working surface - I have no idea how they do it.
Come on VWs! Most other programs have figured this out.
