I’m personally not against “other” or “misc”. Many sites and programs have an “other” section, and there are some settings that truly do not fit into a category.
This might be out of scope, but has there been any thoughts on adding a search bar like site settings? It would make it easier for site staff to help link someone to the correct preference, and also deal with the fact that using Ctrl+F to find a preference no longer works with the individual tabs.
