There are a few tagging categories for threads here and on the wiki. The “Hacks” tag here and the “How do I…” category on the wiki are worth exploring.
Start with the ‘hack’ thread: What patches are 'vital' to your use of Gramps 5.1.x?
Hint: use the Advanced Filters (click the magnifying glass) here on the Discourse to search by ‘Tag’. Click on the Categories hotlink in the footer of wiki pages for an index of Categories.
