Trying to sync up multiple Interval Switches is a daunting task and they fall out of sync soon. It would be great if every 1sec interval was aligned to the game time. That way it would be easy to set up multiple frames in animated billboards for example (when the 1st blinks on, the rest blink off; when the 2nd blinks on, the rest blink off; when the 3rd blinks on, the rest blink off etc). Also, adding a 0.5sec (and maybe even a 0.25sec) interval and multiple ons & offs (that can be, but don't have to be used) would be brilliant. Cheers, boffins.
