Plain and simple, OneUI needs custom icon support from play store. I'm tired of downloading other launchers and them always either being laggy or crashing. Samsung themes just change the preinstalled apps look, and no where near what we all want. Having to be able to download and apply custom icons to default launcher would make Samsungs OneUI a whole lot better!
