Here's my suggestion for xenforo. It's regarding the mini menu bar and links.
Add "your content" link to the extra tab's toolbar.
Here's a screenshot example:
What's changed in the screenshot?:
"Your Content" link has been added, it's the last link.
The link would be: http://xenforo.com/community/search/numberhere to search.
Another great suggestion is:For the "Your Content" page it would include the ability to filter out your posts and your threads.
