That's also what I thought as a Vim user before I had access to Kakoune's multiline editing. It changed my mind and might change yours too if you give it a chance
I used editors with multiline editing capabilities in the past.
There are only 2 usecases where it was of any value to me: If I have to write multiple lines in a similar fashion, or if I have to edit the same thing in a similar fashion in several places at once.
Both can be done much easier by using a regular expression.
I disagree. In the past I've used regex to do that and now that I have access to a multicursor, I won't be going back. I think with regex you don't get the same kind of visual feedback that you get from a multicursor which is why I (and many other Kakoune users as well) like it so much. If you're happier with regex and feel like you don't need multicursor, that's great.
Ditto. I rarely use multiple cursors in other editors, but I use them _constantly_ in Kakoune. I have been using it for multiple years. The composability of the command language is what makes it shine.
