P&ID: Import/Export of the schematic, detached from the entire layout

Overview

Giving the user the ability to save (export) and load (import) a schematic once built.

Use Case / Motivation

Being able to save a completed schematic, and load it in a later moment can improve the user experience, since too frequent code update and refactors may invalidate older layouts as incompatible.

Proposed Solution

How you think it should be implemented or designed.

Alternatives Considered
