If it is any consolation, as a VSCodeVim maintainer, me too. We had some issues at times, a lot of them have been resolved, but that first impression is impossible to get back. Contributions have dwindled from people and I feel like it needs another kick to make it perfect.

Thanks for your work!

FWIW, since recently (can't tell you which version, but maybe a week or two back), my editor has become real unresponsive (2-5 seconds delay when I switch from Insert mode) and if I type before it switches, keystrokes get inserted as text.

If it’s any consolation, Ctrl-R will redo those same fifteen changes, so you won’t lose any work. And the vim extension’s undo history is separate from the editor’s so you can’t really lose any work accidentally.

Yup. I had the same issue with vscodevim which causes me to ditch vscode entirely.
