Color labeled text blocks

I'd love to set color labels for text blocks (Captions) and filter them (preferably multiple labels allowed at once). It would let me see which blocks are checked/edited/important/obsolete and make life silightly less complicated. Thx.

Wait! I just thought about two additional options for that feature: "New sequence from selected blocks..." and "New sequence from labels..." where I could choose any amount of labels (now I think it should work also as custom tags) and create new sequences for each selected label/tag with a single click. That would be very useful for editing many shorts from a long interview.
