Recently I've been working on a project that has a lot of angled lines and then some times for selections or just for drawing i thought about using the cplane tool but using it in orthogonal views its kind of weird. All that times I just wanted to rotate the cplane in xy cause i was on the top view but if I clicked on a line, the tool aligned the new z axis with that line instead of aligning the x or y axis as I expected, i kind of understand why it happened but its just not what i think most people expect, cause the result is confusing (the top view now is the front one and the right is the top for example). I propose that in orthogonal views, for making the tool easier to use, the cplane tool work only in 2d.
