This app allows gives you more control of your start screen.

1. You can create null tiles. When you arrange tiles, you can make some ‘empty’ spaces, but when you arrange tiles into groups, Start Screen always displays miniaturized version of first four tiles. Now, you can create null (empty) tile, put it in group, and voillea, you have less miniatures, and some empty spaces.

2. You can create tiles for web pages. When you create tile for web page from Edge browser, you get tile with web page icon, sometimes very obtrusive. And you cannot differentiate between subpages from same web site. Now, you can make tiles for web pages, and define label for it.

Functionality (1) is present also in some other programs, but these very old programs sometimes doesn’t work (are stuck on ‘Loading’). This is UWP apps, so it works even when such other app stop working.
