On-hold/floated items, and timecode appearance

Is there a way to hide all on-hold (floated) items? They take up space and I don't need to see them.

Also, is there a way to have the on-hold items, be a shade of dark grey instead of red? It's too easy to confuse them with the timing bar, out of the corner of my eye.

As well... the timing for CGs, as it appears in Inception, in the slug, has 4 different timecode values. Is there a way to pick only the ones we want to see?

Thanks!
