I am successfully using flow.get('$parent.foo') in several subflows necessarily located in one, what has become overtime a very large flow, the result is node-red slows to a crawl when I am on that flow page, I want to split the flow on to 2 pages to get over this problem and the easiest solution would be to move the subflows to a new flow.
My question, is there any way to point $parent. to a specific flow page or constrained to having the subflows on the same flow page ( or perhaps converting all the flow.get / flow.set to global.get / global.set
