Agree, it's not particularly customizable, but I've been using it for a week now, and it's been the launcher I've been looking for.
Only issue I've had with it is that sometimes, the web search tries to search as if the query was a domain and not a question. Though that's not a deal breaker.
That's foul, I was considering getting a Poco Flagship for my next phone. Though I guess if you manage to unlock the bootloader and run a custom rom, perhaps it doesn't matter as much if you don't get "HyperOS" updates?
This doesn't really bode well for Xiaomi's future though.
