Holiday requests should only show other staff with clashing dates, not dates that don't clash

Receiving holiday requests along with a list of staff who have the same dates off, is all we need to see. Adding staff to the list who have the week off before and after just pollutes the list and makes it so difficult to read the request. It makes holiday approving a lengthy and scary process as I am never entirely sure I have approved someone's holiday that doesn't clash. The green and blue is also very unhelpful as I always forget which one is for pending and which one is approved - just use words please.
