Thanks for this topic. Yes now it is added to "other" category. However, I added link to GitHub from macro name not from user like everybody above because it looks more clear to me (sorry for that).
Before adding link to the macro I also tested adding new "woodworking" category in preview. So I guess I know how to add new category correctly at the end. To add new category above "others", the "T" need to be recalculated (to expand sections correctly). I found nice icon for woodworking here https://openclipart.org/detail/20280/wood-icon
if you decide to add new "woodworking" category.
