Oh, I love Dear Imgui -- it's very simple to use and has a nice... "engineering"/scientific aesthetic. Good to hear it's been ported to python.

If you're looking for an end-user product, this may not give you the control you're looking for. But if you're looking for a dead-simple way to create a quick GUI for a side project, this is perfect.

From the github page - EDIT: Read the bindings / frameworks page too, https://github.com/ocornut/imgui/wiki/Bindings It's still c++ like.
