Ok i've just found the support forum... so there is my message (also post on http://make.wordpress.org/ui/ ...)
I’m new here and I like the MP6 ergonomy !
But i think we can do more. I’ve made a little plugin to do little improvements.
Look here the result : http://rcrea.fr/img-host/mp6-perso-17-06-13.jpg
If you want the little plugin or more info just ask.
I don’t know how i can help on this, if it’s not the right way tell me ;)
