Hello,
On last versions of Minecarft (PE) repeaters set on like 4th inpulse mode are taking more tike to transmet the redstone signal that a repeater on the firts inpulse mod.But on this version they works everyway like if they were on the first inpulse mod (so they do instantly and not with dew seconds of wait).

How to reproduce :
-Place a button on the floor
-Place next to it a chain of few repeaters on an other inpulse mod that the first (click on each)
-Place a lamp or a thing that show you that it's recinving the redstone signal at the end of the repeaters chain
-Click on the button and you will see that the redstone signal is transmit by repeaters a lot to fast.

By the way even if I know that you don't manage features on the game but will we have a day the /wait command to don't have to do a chain of 10 repeaters on the fourth inpulse mod to make it "wait" only 3seconds ?
