I would like the ability to create conditional controls / inputs. For example, I may have a Select control with bottom margin options: none, sm, md, lg, xl, custom... and only if the Select control value is "custom" then the controls for entering a manual amount of margin will show. The motivation here is to make the editing experience in the visual builder easier, less cluttered, and to eliminate confusion by removing the controls that don't apply. Alternatively, or ideally additionally, it would be nice if the margin and padding controls from the Style control would integrate standard spacing values with an escape hatch to optionally enter custom values. The motivation here is to avoid 1.) having to manually enter consistent margin/padding values when setting up a page layout 2.) avoid mistakes for people creating new content who may not be mindful of ensuring consistent spacing 3.) to make it easier to update the standard spacing values in the future. Thanks!
