SIMPLE TABS is a Blender Addon that helps to organize your N-panel (also called the sidebar). This ultra simple addon is very easy to setup and won't get in the way.

Check out this video for more information:

Created by bonjorno7 and Chipp Walters, this addon does the following:

• reorder N-panel tabs
• rename N-panel tabs
• consolidate N-panel tabs

SIMPLE TABS is not designed to work seamlessly with workspaces. SIMPLE TABS was created for the 3D View N panel only-- which is where 90% of the tab clutter is. Also, SIMPLE TABS automatically does not manage some addons, and for those their tabs are left alone. You can manage the "do not include list" in the preferences.
