Simplify the creation of Custom Properties

(Current state of object custom properties in 4.5 LTS )

A couple of personal notes regarding object custom properties, and how they could be made easier to work with :

• Allow adding and editing custom properties straight from the 'N' side bar.

Or...

• Add visibility toggles in the Custom Properties panel from the Object panel. If the N side bar "Properties" panel is just meant to change or animate the values of the properties, at least it would be nice to have control over which properties we want to make easily accessible and hide that "cycles" property.
• Automatically open the settings pop up when clicking New. I seldom settle for the default "prop" float 0-1 property... So I end up searching the newly added "prop" in the potentially long list of existing properties to tweak its settings.
• Right clicking an existing property should provide a "Duplicate" operator. In order to quickly create a new property based on an existing one, instead of going through all the settings over and over again.
• Manually reorganizing custom properties... Much like panels or Modifiers. The automatic alphabetical reorganization can be confusing. Or better yet, Adding "Panel" properties to sort things nicely.
