All right, so maybe I should take the Getting Started class after all. ^^
I *think* I remember that in some live stream – maybe it was during the sculpt class?, @theluthier very briefly made mention that although he always used left-click select for Blender, he recently saw something that made him realize that the default right-click select is actually very useful in a certain way and he wished he had learned it that way instead, although I don’t remember what exactly it was that he had seen. Am I just imagining all of that? If not, I’m wondering if whether I could or should take advantage of the shift to 2.8 to try and switch to right-click select as well.
