Highlight clip that's open in an editor / Lock clips

[Stone Guest]

When you double click on a clip to open it in an editor I think that the clip should be highlighted in some way - perhaps with a temporary border or a colour change. As it is, there is no good way to identify which clip is actually open and being edited.

OK I now realise that using a darker theme does highlight the selected clip - but I prefer the light theme in which the highlight is not particularly noticeable

I also think that there should be a way to lock clips to prevent them from being accidentally moved or deleted. This is a common and extremely useful feature in many applications.
