Everything.
You are still left with numerous clips - instead of just one - that sit on top of each other. Good luck arranging them or slip-editing them.
That is so incredibly stupid and so useless, the mind boggles as to what they were/are thinking. I think you can somehow group them or something (I forgot the specifics) but it's still convoluted and a pain in the arse and completely bizarre that such an expensive DAW in the year 2021 has no proper function for such a basic thing. I feel all dusty just typing this.
