Enhancement to new "On Object" feature - toggle open and closed multiple panes

Overall I like the updates for the On Object features making it easier to switch to different panes, however, something in the old interface that was helpful seems to have been lost. While I can see that I can open multiple panes, my only option once I've opened it is to close it. I liked before when I could minimize the pane into the side to save space. The current functionality just makes me have to make too many clicks that become annoying when juggling a lot of things in development. This is especially needed now that you've added a panel for the fields list (visual builder) which used to be part of the format pane. So I will typically need 3 panes open routinely, and sometimes adding others as I move around and do various things.
