New feedback from Outlook.com
As far as the different versions, I like the sweep on beta better than the regular one but I still like
the look of the regular one with the square boxes so much better than the beta. It is also annoying when sorting senders to have the headings on it, you can see that they are all the same and it is so much easier to go through emails and select them all for deletion and then uncheck the newest or most important ones. If you could get rid of that or have an option to un-select sort headers that would be great. Also keep the old one's look but integrate the sweep look to the older version.
