I've been trying the new
Nacho Bee skin for a while and .... it's just fantastic

This is definitely the best one of the four, it looks so professional that I even forgot red is not one of my favourite colours !
Congratulations, Sarge

Give us more such a great Skins, please

A couple of minor enhancements proposals (the skin is so good that I had to do my best to find them

):
1. The rating stars are invisible in Mini Player View:

2. The Auto DJ the only tool that is green (unless it's intended):

3. The way that 'Details' and 'Lyrics' buttons behave are inconsistent a little in various places.
Compare:
Now Playing pane in the right in fullscreen default layout:

Now Playing from Mini Player View (press playlist icon to see it):

I would prefer it to change the colours just like the top menu commands:

I've no other suggestions for improvement I'm afraid.
