Update the 'Create a Livetile' page
Since Windows 8.1 it is possible to create a livetile for a website: http://www.buildmypinnedsite.com/en
Only it hasn't been updated since then even though Microsoft Edge supports Pinned LiveTiles aswel.
So I would like to suggest to get this website up to date again. And please make it a lot easier to change the layout of every tile and the ability to easily test if the content you've created is how the Edge would expect them to be for the Livetile
