Add multiplier to pause node

[Ed Salter]

From what I can tell, a simple break handler can be created by using a combination of a Timer node (every X seconds) alongside the pause node. Whilst the Timer node has a multiplier field to allow times of hours to be reached easily, the pause timer node only allows a maximum pause time of 5s. If a multiplier field was added to it, a more realistic break time of 15 minutes could be entered for example.
