Thank you so much!
I'm starting on a data cleanup task (which will lead to table structure cleanup in the future, I hope) on a production database. Well, starting in the development environment, now that we have one (that was step 1....).
I needed a good tool to track the flow and add notes (like code I used in certain clean up situations, or exceptions that I found that need to be followed through to production).
I read this article today and downloaded/installed FreePlane - so far, it's great! All my notes in one place, organized by flow - but I don't need to scroll through pages and pages to find anything.
