Hi CocoDayo,
Thanks so much for your kind words! I tested this in a clean template project and everything appears to be working as expected — I’m able to switch actors with Q or W regardless of what’s currently selected. This suggests that something in your project environment (likely another plugin) is interfering with that behavior.
To continue troubleshooting, please test the plugin in a blank template project with no other plugins enabled and try to reproduce the issue there. If the bug still occurs, you can email me at support@dmplugins.com with a link to the uncompiled project folder, and I’ll be happy to take a closer look.
