Allow Property Pane Groups and Group Fields to be hidden
Richer editing experiences can be written when group fields and groups can be hidden via property pane configuration - much like group fields can be disabled by passing true to the disabled property.
The 'disabled' property is not enough for building rich and dynamic editing experiences. Especially when groups of fields need to be disabled based on other properties. We need 'hidden' as well as 'disabled' and preferably the ability to hide groups as well as group fields.
The current solutions for dynamically showing property pane controls involves creating wrapper controls and frankly when it comes to developing SharePoint sites I'd rather spend development time on the features and not the editing panel when all i want to do is hide superfluous controls when they're not applicable.
