Abolish peek-a-boo UI. It's just bad design.

I was trying to figure out how to drag video from the source viewer into the timeline, without the audio. There was no apparent way to do it.
Oh... unless you accidentally roll into this empty area under the viewer, and then magically two controls appear that let you drag video and audio independently. WHY?
The implication here is that we users are supposed to roll the cursor over every pixel on the screen, on every page of this application, hunting for hidden goodies. Do I really need to explain why this is an absolute design failure? Actually, it's worse than failure: It's not even trying.
Please FIX THIS NOW.
