Rotate Cube: Edge Flip Move - flip delay?

I am using 16.04 (CCSM 0.9.12.2). In a previous version edge flipping with Rotate Cube allowed the setting of a delay on edge flip while moving a window. This was important as near-to-edge-movement is a gesture for doing a half desktop window maximisation. There does not appear to be any option for this in the current LTS version, resulting in half screen maximisation being a Game of Skill™ where the participate attempts to race window maximisation with edge flipping.

Is there a non-obvious option to allow a longer delay before an edge flip occurs?
