But I would like to create a radial menu that makes it quicker and easier.
I have scoured through the HOM and haven't found any way to access the currently active/visible python handles though. How can I do that programmatically? I do not want to create my own custom viewer state handle but instead get the built-in sidefx_transform3d handle so i could change the handlealign parameter, which I imagine I can do when I have the xform hou.Handle instance at my disposal.
