I’ve added an application tile to the app! In order to view the tile you’ll need to press and hold the small application icon until a context menu pops up. From there the “pin to start” option should be available and that will do the trick.

What you should see currently is that the WordPress logo is centered in the tile and the title is crowded in the lower-left corner. I should have a new graphic up and available soon–going to scale the size of the logo down a bit so the logo and the text don’t collide.
