TYPO3 Core

Have the possibility to set a TCA palette as modal.

This functionality can be useful, for example, to separate content fields from appearance fields, maintaining the correlation between the two types.
Nowadays, the appearance fields can become many as different devices requires different appearance. For example, I might want a title aligned to the left if displayed on a large screen and instead aligned centrally if displayed on a small screen.

Use case:
Display a 'Title' field with a button to its right

When this button is clicked, display a modal with the title's appearance fields (vertical alignment; horizontal alignment; size; color; etc.)
