Resizable Popup Window in Lovelace Card Editor

When entering the edit mode of a Lovelace card in Home Assistant, a popup window appears. This window is split into two halves: the left side displays the YAML configuration, and the right side shows the visual preview.

Currently, the width of the popup window and the proportions of its two halves are fixed, which often results in insufficient space to fully view the YAML code or entity names on the left side. This makes editing cards cumbersome, especially for complex configurations.

It would be a significant improvement if:

  • The popup window could be resized, either via a “fullscreen” button or by manually dragging its edges to adjust the width.

  • The relative sizes of the two halves could also be adjusted.

  • Home Assistant could remember the last-used size and proportions of the window for a more seamless editing experience.

This feature would greatly enhance usability, especially for users working on detailed configurations or with smaller screens.

Thank you for considering this improvement!
