WTH - Couldn’t the sub view open like an Entity window?

Couldn’t the sub view open like a pop up window rather than a full page?

Would be useful if I want to operate items from a group individually or create status popups on a press and hold option

Browser mod not capable of doing this ? Need to look at subview seemingly

indeed browser mod can do this. it is all in yaml though, and native would be better

Was just looking for this exact thing. Seems like a wasted oportunity. Did you find a solution to make something work?
