Advanced Sheet to sheet reference lines for technical drawings.

Something to improve upon would be canvas connectors on P&IDs.

• It would be nice to be able to click on lines and vote them up or down or hide them. That would train the model to not show those lines.  If a line is voted down, it gets suppressed, or perhaps the AI gets a chance to try again.
• Lines should not be able to stack.  They need minimum spacing.  
• Make the lines rotate through a color palate when they generate so they can more readily show the relations when pulling several P&IDs in.  
• Never allow the lines to run at diagonals.
• Put little jump over bumps when they cross each other.  
• Allow them to be manually dragged around if necessary.
