Most of these features are part of my plugin GD bbPress Toolbox Pro. The plugin is optimized for low memory use and speed, so it will add a lot of standard forum features, with very little overhead. If you are interested, check it out here: https://plugins.dev4press.com/gd-bbpress-toolbox/.

Putting a lot of features (especially complex ones) into the fucntions.php file is a very bad idea. Functions file is made to be used by the theme, but over years, it is used for all sorts of things that are not theme related. It is nightmare to maintain or to transfer to new theme.
