It would be really cool if those of that have an extensive library of symbols could like directly to them within a Mock Up.
Example: I have a base mock up of a CRM. I have a symbol created for a popup form that appears in various sections of the CRM. Instead of create a base page then a page with the base and the popup on top I could link directly to the symbol.
I am sure I made it sound simpler then it is to develop but hey figured it was worth an ask.
