Save Settings for Panel Position and Size

I fell in love with this program the moment I opened it for the first time, but I wish I could save my workspace layout in a more useful way.

Right now it really just saves the splits of the bordering panel groups, but I tend to pop out the individual panels and rearrange them in very different positions.

Example of my layout: http://pasteboard.co/a4Gpg4PL.png

Could the layout.json file be extended to include something like the following?

"popoutPanelState": {
    "frameEdit": {
        "x": 400,
        "y": 210,
        "width": 800,
        "height": 740
    },
    "layers": {
        "x": 80,
        "y": 79,
        "width": 275,
        "height": 280
    }
}
