Sprint Meter Buddy
Sprint Meter Buddy is a little add-on that most importantly makes the sprint meter movable. It also changes the graphics to a clear bar (which changes color according to how much endurance you have left).
You also have options for turning the flash effect off when reaching full endurance as well as scaling and opacity for the sprint meter.
Options can be accessed by typing "/vsmb" which will open the options window (and allow you to move the sprint meter as well).
