I made it to write one poem, & to learn how to code with HTML & CSS & JS. There's one kinda practical usecase though. You can take notes either freeform or of different types for each paragraph of an essay, where each column is maybe notes of the same type. But you have to constantly resize rows to accommodate changes in paragraph length. It's very clunky. The only reason I haven't deleted it is because my dad likes it. I can't imagine why anyone else would though. It used to have autoresize but it just created wasted space. But without it you have to scroll individual editors.
