Add an Area Selection tool. With this, players could define a selection zone similar to what earmuff mode and avatar culling uses. then it would highlight all interactable things in that zone (users, stickers, prints, etc.) and present them in a simple list or menu. From there, the player could just click the specific thing they want to interact with.
This can greatly help with instance moderation and QoL for individuals who want to hide stuff quickly when there is no moderation in the instance
