Yes, she and Yuzu seem to be getting a lot of solo vocal parts lately and doing really well at it! Honoka has been kind of pushed back though. Seems like all her solo parts are very short and spoken-word based or backed up by Yuzu like in Colors.
Shampoo Hat is brilliant, the arrangement is great, it's electronic but still have real instruments sound. IMO it has potential to be the best song from stardust groups this year.
