Is it possible to have multiple animations running in the same time instead of just in a sequence (eg. two object animations beginning in 0s but each during for a different time)?
Short answer is yes! However, without knowing exactly what you are trying to achieve, I am just guessing here :)
I've attached a project that animates two objects simultaneously. I added an interaction on "Minimize ALL" to trigger a new state. In the new state (Tapped/Clicked Minimize ALL), I made changes to the UI to reflect the end state. Then I dragged out the "changes" recorded in the timeline area.
