+This properly fixes the multi-monitor support for windows(tested only on 10, assuming 7+ will work)<br><br>
+Also supports user defined speed of smooth mouse movement (original randomness updated to alter a bit based on distance)<br><br>

 #### How about multi-monitor support?
-
-The library doesn't have explicit multi-monitor support, so anything that works is kind of on accident. Subscribe to [#88](https://github.com/octalmage/robotjs/issues/88) for updates.
+Multiple monitor support working. Tested in windows only, need additional feedback for mac/nix.
 
 For any other questions please [submit an issue](https://github.com/octalmage/robotjs/issues/new).
