What new services would you like added to the Webmaster console? They are looking for suggestions and are allowing VOTING as well as commenting to elaborate. Of course, out of respect to DigitalPoint, you could also post your suggestions here in addition to Cutt's blog.
I would rather real time data instead of more features. Also a real time PR value to put an end to the pagerank update threads here.
I just voted also, I think this one (More information about penalties or other scoring issues) is great. Webmaster would be able to know and correct potential penalties, sounds good to me.
