When using a sequence that is set to use a single pass, it should either unlatch the button at the end of the sequence or allow that sequence to be run again if pressed (instead of turning the button off). Right now, once the sequence completes, you have to press something else in order to run it again.
Example. I have a sequence that turns everything to full white at full intensity and then fades out to black. If I want to run that 3 times in a row, I have to make sure that I use a blackout button in between so that I can reinitiate the sequence again.
