What is your suggestion?:
Enable bank placeholders for the Cute Creature received from daily login rewards. If the other daily login rewards such as the evil creature and mimic do not allow for placeholders yet either, it should be added for them as well.
Is this in OSRS?:
No, but you cannot obtain the Cute Creature as a follower on OSRS anyway, so the point is rather moot
Has this suggestion been accepted already?:
Not that I could find on the pinned thread
How would this benefit Alora?:
Pets are something often removed and readded to a bank as players want to take ones out for fashionscape or other reasons. At least among skilling pets (I've not received any others yet), these can have a placeholder given, allowing a user to maintain the ordering of their bank while still displaying their pets as they desire.
TL;DR: bank tidiness is a better player experience
