Visual previews for predefined block types (when adding block)

It would be very useful and great to show a visual of what the block looks like before adding it, while giving users the predefined block types.

@Ahmet Bora That feature would be awesome for our clients. Sometimes we have mor than 30 blocks :)

For now, you can use this plugin: https://github.com/junohamburg/kirby-visual-block-selector
