I'm interested in designing a mobile-friendly search results page where users can refine their results. I'm thinking about using a left-hand sidebar with the filtering options rather than a top section which would use up a lot of the results section. This layout would be similar to [this Dribbble project][1] (pictured below). [![enter image description here][2]][2] Are there usability reasons for this type of navigation not being very common on mobile devices? The sidebar with the icons would be expanded upon click to view standard text-based filter options. [1]: https://dribbble.com/shots/1005661-Whatsapp-flat-redesign [2]: https://i.sstatic.net/5qPd2.jpg
