Hi
Just a quick hack, if like me you find it extremely irritating that the code window opens over the top of the properties sidebar:
Right-click on the page to Inspect.
In the Elements tab, find the div element <div class="formulaBar_8bt9hy " ...
Give it a custom width of whatever suits and lines up with the left-hand edge of the expanded right-hand sidebar. In my case my monitor is 1920px wide so I set it to 1543px.
Then find the right-hand sidebar which starts with
<div = class"controlSidebar_1hs93jy
Adjust style, set top: 44px
Should look like this now:
There's a way to get these adjustments to persist on your browser using Sources > Edge Overrides but I couldn't get it to work as yet.
If you need a bit more space you can also hide the header (<div id="header" ...) if you like by setting display:none.
If you have any ideas for getting these hacks to persist please reply.
