What PropUI does

PropUI turns custom properties into proper Blender UI. You author a list of controls in a visual editor, arrange them into a layout, and press Generate UI. PropUI writes a normal Python panel — stored inside your .blend as a Text datablock or exported as a portable .py file — that keeps running even when the editor is closed.

The generated panel is an ordinary Blender Panel. It can live in a sidebar tab or a Properties editor tab, drive custom properties on almost any data owner, and show or hide itself based on what is selected.
