Speed up labeling

I found a new tool makesense who is trying to do the same thing that you're already doing. Probably with some new thoughts in mind. I recently asked the author how that tool is doing differently: https://github.com/SkalskiP/make-sense/issues/23

The author responded that we need multiple clicks while labeling in imglab. Though I didn't understand it well as I can control most of the things with tab or other hotkeys. However, is it possible to simplify the view to speed up the labeling process?
