This add-on is a must-have if you are into customizing your interface. It gives you the option to completely create your own pie menus, regular menus, side-panels and toolbars.

You can create your own macros or insert the tools you use into these menus and toolbars as well as choosing shortcut keys.

While it takes quite some time to set this up, it only needs to be setup once. From there it is a time saver every time you use Blender.

If you have workflows you use over and over. For instance, you may have certain modifiers you add to objects over and over, you can create a macro to have them setup with the click of a button. You can also set up pie menus with all the tools you need and hide large parts of the interface to have a clean workspace.

The major drawbacks are the time it takes to set up. The documentation has also become outdated and would need a refresh even if it is still helpful.

There are lots of possibilities with this add-on.
