In my case, a screen may include up to 10 states, but some time, I need to add new “Loading UI” state at the beginning of the screen (at State 1). So I have to addnew one state and shift all exist state right. I take effort and may make layout of the screen become confusing.
In some case, I need to insert a state at the middle in order to “Re-Use” some components of Pre-State (just only extent it).
thank you very much !
