COMMON PROBLEM - The majority of users start-screens start looking like a mess after a few months... particularly with many installing more apps than before (METRO).
SOLUTION: Would it be possible for Microsoft to implement the following two features to better organise the Start-Screen and keep it looking in great condition? The two options I propose are:
Smart CATEGORISE - This would automatically categories any apps into the default Windows Store categories (including any future apps).
Smart FIT - Smartly adjust/fit the mix of live tile sizes so that the full column height is used (where appropriate)... and adjust accordingly once new live tiles have been added (After a certain number of live tiles have been added giving the user the option of adding another column to the group).
I hope Microsoft at least considers my proposals as I strongly feel they will benefit most users... particularly novice users.
