The current implementation of direct mouse flight control is touted as being WAC-styled, and comes so close, but is made unusable by the fact that the mouse never automatically re-centers, as it would in WAC, leaving it as more of a "direct mouse drink-and-fly simulator".

An additional option to have the mouse status automatically reset without direct input (with options to make the timing as tight as possible) would go a long way to truly recreating the weightier feeling of good ol' WAC, for those who want it.
