As far as I can tell, the Vim mode in Fleet isn't even able to save files yet, which I feel like is literally the first thing I learned to do in Vim. I'm not really sure what it's even supposed to be able to do yet because it's missing so much that it's not worth the time for me to invest in playing around with it.
Sorry, I didn't read carefully, not realizing you were referring to Fleet. I have not used it before.
IdeaVim in the pre-fleet Jetbrains IDE work well (enough) for me. Tried with WebStorm, RubyMine, AppCode. I think I wouldn't use them as much if IdeaVim didn't exist.
Yep, I like the Vim plugin in their IDEs, and I'd be thrilled if Fleet provided that level of functionality for its plugin, but unfortunately it's not clear when that's going to happen, if ever.
