It would be nice in the designer to add custom properties to Folders. I know this can be done in scripting however it is not discoverable in the designer (only in scripting). Use case: i would like to add a custom property to a tag folder to filter upon to either hide or display the children tags/folders or not in a perspective tree component. Whilst it can be done in scripting its completely hidden within the designer so will be hard to identify. Ive noticed in 8.3 foldres now have some alarming stats so it would be nice to extend this further.
