Snapping - Account for Dock on multiple monitors

Hello,

OSX multi-monitor support is a lot better than it used to be, and one thing I love is how the Dock will 'move with me' from screen to screen. However, when I 'maximize' a window using BTT, it accounts for whether the dock is present on that screen and, if it isn't, maximizes completely.

It would be nice to have a setting to ALWAYS leave space for the dock, so that even if it's not on the monitor at the moment, it's the right size to allow for the dock once it does appear.
