Implementation of share screen on mobile devices

[dewanshDT]

Feature enhancement details:

currently in mobile devices the editor is all cluttered up and shows unresponsive design

Instead of showing we can Implement this according to zeplin designs

until the mobile view of the editor is made showing the share screen would be a great thing

I want to know if this has to be implemented, and would like to work on this @raclim
