I have a scene with multiple characters and multiple rigs. It annoys me to no end that [A] selects all armatures at once, not just the one active. Also when I select some bones in one armature, sometimes there’s one forgotten extra bone from another one across the screen, which I don’t notice and animate by mistake. I have to hide armatures every time and it’s tedious.
I understand multi-armature selection can be useful, but it shouldn’t be the only way. Is there any way to get 2.79 armatures back?
