Many windows just disappeared from the plugin menu. Where can I find the data for these?

It looked nice at the beginning, but after restarting the computer, all the windows were damaged and there were 20 of them

This addon helps me a lot, thanks. The only thing that is missing is custom keyboard shortcut to instantly go to the next window. With that addition it would have been the perfect workspace management addon in my opinion (and my use case of course). So i hope you can add that ability in the future. Happy new year.
