Summary

Hey :) When I open Rhinoceros 3D and then attempt to open its plugin Grasshopper, it doesn't launch. I'm guessing it's because Grasshopper's window isn't independent, but belongs to Rhino. As an example, you can't have only Grasshopper's window at the top of the window stack without Rhino also showing up.

To get around this, I've excluded Rhino from Komorebi, but that's not ideal as it occupies all workspaces :/

I don't know what other info I could provide, but if you have any questions, I'll happily answer them.

Looking for configuration files in C:\Users\mm1351

Found komorebi.json; this file can be passed to the start command with the --config flag

Found C:\Users\mm1351\.config\whkdrc; key bindings will be loaded from here when whkd is started, and you can start it automatically using the --whkd flag
