parameter collection panel

It would be handy to be able to drag any parameter in the UI into a parameter collection panel. This would allow you to control properties for various objects without having to select them, and for controlling properties within the UI without having to navigate to different areas in the UI...everything you regularly need you could just place in the param collection panel.

You could also have multiple set of parameters in one panel, accessed from a dropdown, similar to the dropdown in the text editor where you select different texts, or the dropdown in the world shader editor where you select different worlds etc.

Basically custom UI's without the need for python. Additionally these could be converted to Python automatically for sharing.... similar to the HDA system in Houdini.

It wouldn't only have to store parameters, it could also store operators by dragging them from a menu or from the f3 menu.
