I'm finding that even when turning off other player's graphic effects via the UI during raids, that there's so much fight-encounter graphical flashing going on that it's difficult to find the mouse at times.

The sonar setting adds to the flashing. The software mouse options introduce lag in the raid environment where lag can kill me and thus likely cause the group to wipe.

Can we please have a UI setting that allows the mouse size to be set (similar to the 'scale window' from 60-200%)? Being able to choose mouse color (e.g. have it be white on a black background and vice-versa) would also be great.
