This is a plugin that let you drag nodes from a panel to your current edited scene.

How it works
To generate the list the plugin just retrieves the whole class list from ClassDB
, filters it a little and add the results into a Tree
node. I made it a Tree just in case search functionality is added.
The drop stuff just adds the node to the current edited scene and then moves it.
