Hi @kurisu-io,
This feature is not being actively worked on at the moment. We’re focusing on the last pieces of 4.15.0 and all our devs are trying to finalise that release as soon as possible.
If you could describe your use-case for hotkeys in windowed mode a bit more, I can make sure to update our dev’s on this, as it will help us prioritise what issues / features to focus on going forward.
Kind regards,
Martin
