A: Hi, thank you for asking this.
We don't have automated tracking at the moment, but this is something which we have been discussing a lot internally. Specially with the sort of crawling tools available at the moment, we do feel this'll add good value to the product where comparing the changes would be 3-steps easier. Adding it to our roadmap 🚀

As for feedback history and pin context to remain intact - Yes, that's available at the moment. Whenever anyone drops a pin or comment, a screenshot is captured and attached to always show how it looked at the moment the comment was entered. And all these comments and screenshots are tied to versions to always come back and get the complete history 💯
