Scripting API - Allow tools that are grouped in a drop-down #3241

I am creating a custom tool that places a "warp object" (custom object with custom properties). I do have different types of warps, but having all those different tools in the toolbar is kinda cramped. I think it would be nice if a tool could function as a dropdown... or there was a ToolSection-Object which would then display collapsed and the user could press the tool to get the actual selection of nested tools to choose from.
