I’ve never used it but since it’s basically a kwin script I’d bet you can change them in system settings, like in system settings -> keyboard -> keyboard shortcuts -> Window management (or however it is named in english) -> look up for krohnite
E: Or maybe, just maybe, in its entry in the Kwin scripts section - System settings -> Window management (or however it is named in english) -> Kwin scripts -> Krohnite -> Click or tap the cog button -> maybe there should be something related to keyboard shortcuts
I think it’s better for Linux to grow its base organically and the best advertisement for it is its own quality. But maybe that’s just me.
