Allow custom Icon Packs One Ui

[BenGinders]

The icon packs on the Galaxy Theme store only cover limited apps so looks odd with only a few icons themed.

It would be great to enable users to apply custom icon packs from the play store.

That's literally my only reason to use another launcher: be able to use my icons from the play store

Pretty please, i have a couple of themes from the store that I would love to add to my default launcher.

It would also be great to customize the icons individually as Nova Launcher does.

Although Nova Launcher is a great launcher, but the One UI has a fantastic integration with the system mainly speaking the night mode and wallpapers.
