How to make posed model stay in place in edit mode? How can I make the model stay in posed postion while ive use edit mode?
Because when ive loaded saved pose, and use edit mode mode model return to default standing pose.

I have noticed this problem when my model seats so ive wanted fix it
but it is not visible in default standing pose.
I guess what you want is to enable the On Cage option in the Armature modifier. It has a downside though, if you select a vertex, the Move gizmo won't stick to the vertex pose position but to its rest position. It would make more sense that once you enable On Cage, the gizmo sticks to the vertex pose position.
