Global popover set?

I created a set of 12 Playing Techniques to use in popovers. Worked great in my project. Then I started another project. The new popover set doesn’t work there. Do I have to build a new set with each new project?

No, but you do need to click the little star icon in Library > Playing Techniques for each of the custom playing techniques you’ve created, so that they are added to your user library and will then appear in new projects you create subsequently.
