I think the trouble is they hide the little buttons that make these things toggle, and if you don’t know how to engage a facility, you’re stuck. Premiere, for example, as a nice feature that actually lets you grab everything on the right of the cursor, so you can drag everything forward to create a ‘hole’for the new clip, or you can do it automatically. Oddly, I don’t tend to use the auto facility – and I don’t know why?
