UI Page - Can You Remove Margin?

Hi Tallman,
Ok, so adjusted some settings like so:

config:
  label: PanelV2DEV3
  sidebar: true
  hideNavbar: true
  layoutType: fixed
  fixedType: canvas
blocks: null
masonry: null
grid: null
canvas:
  - component: oh-canvas-layer
    config: {}
    slots:
      default:
        - component: oh-canvas-item
          config:
            x: 1
            y: 1
            h: 1200
            w: 1920
          slots:
            default:
              - component: widget:PanelV2DEV
                config: {}

Which is better, but still has space to the left:
OpenHab-canvas-left-space
This space is in both Edge and Chrome, full and “normal” screen.
When using the Developer Tools (F12) I can see the elements broken down like this:
class=“oh-canvas-layout”

<div class="oh-canvas-layout-container" style="user-select: auto; width: 1280px; height: 720px; transform: scale(1); text-align: center; position: relative; --oh-canvas-item-box-shadow:0px 0px 4px 2px #444; --oh-canvas-item-svg-shadow:drop-shadow(0px 0px 4px #444); --oh-canvas-item-text-shadow:#444 0px 0px 4px;">

is this:

Within that div is this div:

<div style="height: inherit; width: inherit; position: absolute; top: 0px; left: 0px;"><img class="oh-canvas-background">

I’m not sure whether it’s something I’m doing wrong (very likely) or a bug.

Thanks,
Richie
