Pie Menu Editor 1.18.7

To make progress on the following problem:
https://blenderartists.org/t/free-animation-kit-needs-your-help/1189275
2 important questions to be answered please:

1.)
Is “Pie Menu Editor” capable of switching between pre-created custom workspaces,
in order to switch between different workspaces more easily via pie menus than with
tedious default top bar side scrolling?

2.)
Can I save & export custom pie menus created with “Pie Menu Editor” and distribute them for free to people who didn’t purchase and install “Pie Menu Editor”?

Thanks for any clarifying information.
