Remove forum parts

[TheFlash]

am asking if it is possible to remove the forum sections themselves, what I mean is. categories/general-section.222/
general.3/

like remove all of them these two are examples for you to understand what I mean. Have a single forum where you start a thread about anything without having to think about which sub-forum to start the thread in. A little like X and a little like Reddit. There is no direct forum without a feed. Does it work?

There is a little arrow button on the right side of the bar, the bar thats green. If you click on it it will hide the category of that forum all together
