Just wanted to say a huge thanks for implementing this!!!  It has made my Windows 11 experience much better than Win 10 so far, as I was able to somewhat reproduce my favorite feature from Windows 8 - a customized start screen (back then using the now defunct OblyTile).  I have about 80 tiles so far (not all of them have/need custom images though).

I do have one request in this regard though:

Right now if a custom icon image is used, there is only one line of descriptive text possible (with "standard" icons there are two) and it is not possible to change the tile "background" color.

It would be nice if the tiles supported transparency in the custom images (a .png with transparent surround for example) which might allow both being able to specify a color for the background as well as make space for a second line of type if the non-transparent part was small enough.

Once you get the 'Never combine taskbar buttons' function out to us, Start 11 will be nearly perfect!
