This is your chance to give the Webmaster Central team your ideas and have the SEO community vote on them. The more votes your ideas get, the more likely the Google team will work on them.
The Google Blog post links us to the Product Ideas for Webmaster Central Google Moderator section. There you can submit new ideas or vote on existing ideas. Currently there are 72 people have submitted 55 ideas and cast 609 votes, which is pretty low - so get in there and get voting.
The top ideas currently are:
"In [Links to your site] I would like to see an additional summary view that just shows the domains that are linking to my website rather than individual pages. This will help me to easily see when word of my website has spread somewhere new."
"Make webmaster tools part of Google Apps so that I can give people in my company access to our webmaster tools. Right now, we have to setup each person individually using a consumer google account."
"Provide a "history" of crawling errors: how a domain and its errors are developing over the last weeks / months (less 404 etc.). It would be very useful, especially if the site structure and paths have changed."
