A quality-of-life improvement would be to have the ability to move:
A Variable/Selector from one Variable/Selector Group to another (either 1 at a time, or multiple at a time)
A Variable/Selector to another Variable/Selector Group in another section or page (e.g. either 1 at a time or multiple variables/selectors from a Variable/Selector Group in “Design” page to a Variable/Selector Group in “Other” page/secdtion)
Without having to copy/paste an entire Variable/Selector group to another page/section, then deleting the extraneous Variables/Selectors I didn’t want switched over.
