Hero web part - Tile description to display on user focus (mouse over)
It would be great if the description field that is available in the Hero "layers" layout was available in the Tiles view as well,. The behaviour would be that the description would overlay the tile image (would need a gradient background so text is readable) when user has their focus on the tile - i.e. for mouse users this is "on mouse over" for keyboard users when the user first tabs to the tile
