Is there an easy way in xLights to slice a single long effect into two short ones? Let’s say I have an effect 40 seconds long. If I want two 20 second versions, I have to grab an end, shrink it to 20 seconds, then copy and paste. It gets a little worse if I want unequal divisions. Sorry if this is a newb gyration, but I can’t find anything in the manual or videos.
