Thank you for the description of your approach, @Port!
I also do use @gncnpk’s scripts. Not only A tool for filtering edits on Google Maps by status and type for tracking the edits , but also A tool that makes filtering photo/video contributions easier to track photo views and identify hidden photos.
In both cases, I only use a single function of the scripts, the Auto Load feature. After scrolling to the end, I open the developer console and copy the underlying HTML to clipboard and wrote some Python scripts which extract the essential information and converts to a CSV format, which I then paste into spreadsheets for further analysis and tracking.
Instead of setting markers in Maps, which I also tried for a short time, I keep the permalinks now in my spreadsheets. For some of my road edits, I copy the little map of the email also into the spreadsheet.
BTW, for road edits Gavin also created A tool that brings quality-of-life enhancements to road editing which reduces some of the repetitive tasks when adding roads.
