What's the difference between multicursor and visual block? Genuinely curious, is it that things don't have to be vertically aligned? What's the ux expectation in a pure keyboard based workflow?
Yeah I think that's it. You can place the cursors arbitrarily with Ctrl+mouse3 in editors like VSCode, ST3, IIRC. Multiple cursors in one line is a scenario I don't think visual block would be great for. I say this as an nvim user who uses macros and will occasionally copypaste a block into VSCode just if i'm feeling lazy and want to multicursor something.
