1. Browse various sections available under different categories to insert in your web page
2. Preview sections in your web page by hovering
3. Buy sections to insert in your webpage

Idea : Have one space on the whole website builder screen from where user can edit properties of the portfolio page, buy new components.

Benefits :
* Saved screen real estate for small screens
* Familiarity for designers who work in sketch, photoshop, illustrator and Invision studio - as they are our target audience.
* Faster loading times since the design is just tabs and drop downs under the hood.
