Would love to see this in Blender as well. As someone who learned UV mapping from using Autodesk Maya in the past, this feature is something I have really come to miss.
Also, fantastic work so far, @sidd017 ! I know this may fall out of the scope of this current project, but one feature I always wanted to see in Blender is the ability to see UV maps of objects outside of Edit Mode (i.e. Object Mode). Always been a major gripe of mine since I moved over to Blender. If you decide to continue working on developing UV mapping features after GSoC is over I would hope that you consider this feature as well.
