The new BuddyPress Extended Settings plugin is very useful for admins who don’t want to have to add a bunch of plugins and code snippets for certain small community-related tweaks. It adds a new tab to the BuddyPress menu that includes an easy way to put profiles on the root, show the profile tab as default, allow special characters and uppercase letter in usernames, disable customer header, control avatar sizes, etc.
The plugin’s options tab becomes a natural part of the BuddyPress settings menu. Overall, it’s very unobtrusive but is packed full of powerful settings. Download the BuddyPress Extended Settings plugin from the WordPress repository and start tweaking.
