Sounds like a good idea, but I also thought "do we already have an “app store” in a Playground face?". So maybe better adding more stuff to Playground in near future.
Assuming that, for example, we can’t change fonts without the root, or we can’t do many customisation tweaks like other brands do (someone wants it so hard idk even for what). I’d wanted to change the font tbh, because I have a personal brand font that I use in my work socials (that one from Google fonts collection, not personally-created). But if no — the no🤷🏼♀️ not a big deal.
