Improve productivity of the UI
The Home Tab needs a re-design - Please focus on Productivity
Here it how it should look

You did that by customizing your Ribbon, right? Is that not enough? The look that you are suggesting doesn't have many labels, so you have to hover to know what something is. It would also be quite intimidating for beginners.
A better idea might be to have an "Other" tab in the Ribbon.
