How to Improve Forum Navigation and User Experience

I have been spending a lot of time on Muscle Talks lately and I think the current layout is getting a bit crowded. As our community grows it is becoming harder to find specific training advice without scrolling through dozens of pages. I am wondering if we could implement a better filtering system for the subforums.

When I use my laptop in Chicago it is fine but on my mobile device the sidebar takes up way too much space. It would be great if the developers could look into a collapsible menu for the category list. I have seen this on other big forums and it makes the user experience much smoother.

What do you all think about the search function? Sometimes I type in a specific brand like Rogue Fitness or Gold Standard Whey and the results are not very relevant. I am curious if others are having the same issue or if I am just not using the advanced search correctly.

I love this place and just want to see it stay organized as we head into the summer months. Please share your thoughts on what would make the site easier for you to browse during your lunch break or gym sessions.
