The ground pour feature shows a very fat, dashed outline. In practice, this obscures designs too much, and make it really difficult to use. Ideally, the outline would be a single pixel width, perhaps even with transparency. For selection, I suppose clicking any of the control points would work, or you could consider alternate mechanisms. For example, 3D software lets you [some-hotkey]-click to alternate between selection of objects at different depths. I'll be happy to discuss! Important to me because: UI is important! Though this in itself isn't the end of the world, I feel removing as much friction as possible and being consistent is KEY to a good experience, and allows designing circuits faster and better.
