The reason I think mentioning mat leave is important is for reference purposes - otherwise your referee may disclose this without your knowledge.

I just think it should come from you.
I would wait for an interview before disclosing such information, I also wait until the interview or just after to provide referee details. I only want referees to be contacted if there is a genuine interest in employing me. To me their contact details are confidential and should be handed out carefully.

I also like career adjectives being listed or at least a brief summary about yourself at the start of the resume. I have one on mine, is just summarises things like years of experience eg 8 years Finance experience, strong skill sets (can work alone, or good team player etc), major achievements etc. It saves the reader trying to work that out from your work history. I have received a lot of compliments on my resume, especially from recruitment agencies.
