my-pattern.cloud which was developed by Jason @MrDoo is a tool that bears looking at. This was initially presented as a tool for uploading and sharing patterns. It is that but I believe it has more usefulness than just a repository. I have been poking around the GUI and found that it has some very useful features to look at a pattern to analyze how it was made.
NOTE: everybody on this forum is automatically added as a user to the group Valentina Forum Users on the my-pattern.cloud site, so you can all go look at the patterns there. I discovered this particular way of looking at a formula inside the pattern. Maybe once we get the GUI documented a bit more this program can be appreciated for the workhorse it appears to be.
