In summary, making this so 'casual friendly' (sinceresly, if I was a more casual player and saw how the display sequencer worked to make a show, I wouldnt want to touch it not even with a ten foot pole and would continue making normal parks), and similar to the track ride sequencer, has made this super hard to use. And it doesnt help either that the music is displayed in minutes and seconds, while the fireworks are only displayed in hundreds of seconds and miliseconds after you pass the 2 minutes mark, which makes them even harder to place in the invisible timeline.

Its absolutely horrible, so so bad, I need to have the game opened in window mode with a smaller resolution, and have sony vegas opened in another window with the same track to see the wavelenght of the song in a timeline, and see the exact second I need to add to the firework I need to use in that exact moment. And chainging the seconds by hand instead of actually moving the thing through a timeline is so so slow, that was not fun when building a coaster, but its even less fun doing any kind of show with the sequencer now. The real problem begins with the miliseconds no good timeline, impossible to know exact effect duration of each firework, impossible to know where to place each one without testing the thing multiple times, wasting a lot of time to desing anything remotely a little bit more complicated than attaching some fireworks with zero sound. Music and fireworks are completely separated menus for the same thing, not impossible to work with, but cumbersome.
