Floating window lock

[tenpoundtoons]

Is there a way to temporarily lock the positions and dimensions of floating windows/panels? For example, when drawing, I may accidentally grab the border of the timeline and stretch it out of place. It's a minor inconvenience, but it would be nice to have a lock button on each window.

Thanks,
Mike

Nice idea, we just have to figure out where to put the icon (there are so many of them already !).
