Problem: We have links for preference tabs. We don't have links for individual preferences in those tabs.
Proposed solution: Have links for individual preferences the click of which highlights the said preferences.
Who would benefit: Everyone, mostly new users.
More comments: Many times in help requests you'll need to toggle on or off certain preferences. You either get told to do so, or tell someone you're trying to help. Currently you can't link to individual preferences, only to their tabs. This complicates matters with new users who may get easily confused, especially when what you're talking about is not in the same language as the one they're reading their preferences in. Having links for them would make everyone's lives easier and greatly tone down the need for screenshots in these cases.
