I would like to join points from two different features. I already searched for plugins but so far but didn't find one working plugin or solution for my task.

So here is a picture of 2 polygons/feautures: http://imgur.com/cQRSpLK

I already marked 2 points and these shall be merged with the other both on the left side. So at the end I would like to have one polygon and the 4 points in the middle for sure shall be 2.
