I also figured out that I can delete last point of line by clicking on point, but I wasn't able to delete whole line - there always stayed three last points. And I would like to ask why, when I click on point somewhere on point line (except the first and the last point) it will add two points around it?
There are two types of line markers: white and semi-transparent grey. White rectangles are actual line nodes: you can move them, and line will change. Semi-transparent rectangles are "virtual nodes": if you drag one, it becomes a real node. This way you can add nodes inside a line. That's why two extra points appear: virtual node becomes the real one, so two new virtual nodes are drawn, so you can add more of them.
And try clicking on a line itself, away from its points. There will be a popup panel from which you can change line color and delete the line altogether.
I plan to write a translatable user's guide, since the need for it is obvious. Probably later this month.
