No individual clip in/out?
How about individual clip editing, such as the rather fundamental setting of in/out points. There are numerous fundamental editing tools missing from this mess. The FREE iMovie beats this awful mess.

You can set In and Out points. You do so by clicking the 3 dots icon and then choose > Open. Check out the documentation. Keep in mind that this is 1.0 application. It's going to get a lot better as time goes on.
