This is something I use on my own sites that I packaged into an add-on so I don't have to go into templates to do this ever again.
I find XenForo's navigation system full of clutter that than be reduced and there some big add-ons that are full of navigational clutter due to how XenForo's navigation system is designed.
This add-on consolidates "Your content" and "Watched" pages with scrollable tabs so you can reduce navigation clutter.
I'm not gonna post screenshots of every page...
