1. Why does this need a custom version of ACE?
The normal version of ACE limits the movement speed coefficient to 1.00, which breaks UMO.

2. How do I use pacing?
Go to controls > configure addons > UMO moves, and bind away. Also use this to change keys for the acrobatics and such.

3. Does this work with Enhanced Movement?
It should, and it did last time I checked.

4. What versions of ACE should I use?
Cobalt or Indigo. Former is old medical, latter is new medical.
