A lot of the times I want to drag a longer clip onto a crowded timeline, which can cause issues and bugs with in-between fades for the clips. This is why I put those clips at the end, edit the smaller part I need and squeeze it in where I need it. A little secondary placeholder timeline would come in handy, like a sketchbook, to prepare a clip before I feel ready to drag it directly to where I need it.
Does this exist within Movie Studio Platinum?
