Feature request: input negative digit

I wanna input negative value in oFusionTextureUnit's property

ex) U or V of Scroll && Rotate && U or V of ScrollAnim && RotateAnim

And also, multiple XForm is not allowed in oFusion but in OGRE Material sytstem it is possible.

Or plz add XFormType scale and scroll. (which changes both of u, v)

Best regards

I added this to the list, expect it to be in the next update
