I spent about a month trying to get used to Kakoune. It never clicked with me and I went back to vim.
My biggest beef with Kakoune’s editing philosophy is that it seems to emphasize “editing in the large” as its preferred mode of interaction. This is totally backwards to me. Editing in the large (making multiple identical edits throughout a buffer) is a rarity. Most edits in day to day use are single edits. So the fact that Kakoune likes to leave a bunch of extra cursors in your wake (like a trail of breadcrumbs) as you jump around a file to make single edits is extremely infuriating to me, like it’s trying too hard to be helpful.
The irony of Kakoune using a clippy-style contextual help window is not lost on me!
