Hello!
I'd like to make a suggestion for a visual improvement to the Windows 10 start menu.
In the current version (1.4.5), when the option to "round the corners of the menu and menu elements" is on:

and we use a custom tile image with full opacity:

results in a tile that does not have round corners (just as an example I'm using a back square image on the Notepad tile):

My suggestion: when a custom tile image is being used and the "round the corners of the menu and menu elements" is turned on, apply a rounded-corner mask to the tile image.
