A lot of people want to switch template in Joomla when their website is browsed by smartphone or tablet, especially since the websites have become responsive.
Recently, from 10 January 2017, Joomla! Extensions Directory (JED) requires that all new submitted extensions should implement the Joomla! Update System.
To create a Joomla template from scratch can be very hard if you are not a code wizard. You need to have knowledge of HTML, CSS and at least few basis of PHP. It requires a lot of time to be built, for testing in all the browsers, mobile and desktop.
