The vertical bar has always made sense with me—it lives in-between letters, for example: when I see "test|ing" I know that my cursor is in-between the final "t," but before "i." If I type "X" I'll get: "testXing."

By contrast, in this app the box cursor is like this: "test[i]ng" and if I type "X," it's not obvious to me that I'll get "testXing" instead of "testiXng."

I get that this is a matter of preference, but I'm curious to know why underscore and box would be preferable to vertical bar.
