E24 Most of the default apps are from AOSP, so those developers would need to be the ones making them look nicer.
This. I don't know if GOS apps are copies of AOSP ones, I assume it is, for simplicity. If someone could be found to make the GOS apps "prettier", adding functions etc, I assume that won't even be really welcome, as it won't make it possible anymore to just "copy" the AOSP apps for usage in GOS adding work. Means, if those apps shall be enhanced, one should do that directly upstreams in AOSP. I'm not aware of how it really is, but from hearsay, only devs are accepted/allowed to make anything in AOSP, any requests, suggestions and everything else, from "normal" 3rd party people, shall just being closed categorically. If that's true, there's nothing to do. I doubt any "prettifications" or other improvements, as good as they'd be, won't ever find a way upstream into AOSP...?
That's a topic I'm personally interested. Must have to join matrix to ask the guys personally...
I like GOS' UI in general, simple and elegant. But the AOSP apps aren't.
