Google announced on Google+ that they are asking for feedback on Google Webmaster Tools, specifically a user experience study.
It sounds like they want to look for ways to make the tools easier to use, more logical and more user friendly.

We want to conduct a quick user study about your experience on the site. We welcome people of all levels of experience to participate. If you're interested in filling out a questionnaire or participating in a one-on-one video hangout, sign up here: http://goo.gl/forms/5VJYKP15Gw
The questions Google will ask you include "why you used the homepage, how you navigated around, and what issues you may have encountered."
This will be done over a short Google Hangout or a questionnaire they send you.
So if there are usability issues that bug you with Google Webmaster Tools, this is your chance to let them know.
Sign up over here if you are interested.
