Thank you for trying Test Studio.
Please elaborate a bit more what do you mean by "recording mouse movements". Do you want to record a clicks, hover or just a movement?
A way to play with the mouse coordinates is to Invoke "Blind clicks" and then adjust the coordinates of the click in the step properties according to your needs (see the attached screen).
Test Studio doesn't record the X Y coordinates as the mouse is being moved. If I'm missing something please elaborate a bit more on your scenario.
Thank you for your cooperation.
