Dashboard Customization on Mobile (Companion App) without the card-preview area

[andyxpert]

Hello great developers of this amazing Home Assistant that I've been using for the past 8+ years with amazing results :)

Since our dashboards are getting heavier and more complex and because most of us use dashboards that have over 1000 lines of config... would it be possible/ok to have an option to hide/disable the preview-card area from the Dashboard Customization while on mobile ??

For me on the mobile dashboard it's a pain-in-the-neck to customize anything on it while on mobile (be it a strong iPad or a simple Android phone) and most of the time rely on doing the customizations on desktop (where it flies, to say the least).

I suggest having an option to disable the rendering of the cards while in edit-mode as that part takes 99% of the load and only show the card config part (the left part of the customization screen) that would allow us to do the changes required while still using the nice GUI for the card config.
I know there is the RAW configuration option, but sometimes because of the YAML indentation it becomes really tricky to move stuff around in text-mode and having the GUI would be way faster/better.

So... technically I would add a toggle in the Config Popup for dashboards to show/hide the cards-preview area (the right-part of the popup), or even simpler to have this toggle somewhere in the Companion App config.

Thank you and keep up the great (and stable) releases !!!
