Hi!
I'd like to add some application as "favorites" in order to have the most used application on top and the others divided by categories in the bottom.

Something like this:

the image above is made with 7 rows of custom css:

.category {
 order: 10;
}
.category[data-name="Favorites"] {
 order: 1;
 width: 1680px; /*don't leave me like this*/
}

I didn't see a way to order my tags, and I didn't see a way to mark some application as Favorite, that's why I'm opening this FR
This feature does not have to be limited to only Treat Tags As: Categories but I think it can work best in Treat Tags As: Tags to have always on top the user favorite application.
