I've used the new Beta for several image sessions and the dither every "x" feature is a HUGE improvement particularly for short exposure capture.
One way that this can be more useful, would be if you could set the parameter in the Event, rather than as global. This would allow more automation and you could change the "x" value for each filter.
This would be helpful for LRGB, where you could have more frequent dithers when shooting with RGB where you would have fewer sub counts, and less frequent dithers for LUM where you have many more subs.
Not sure if this could be easily added....
