Actually uses a real backend neovim instance. Can’t get better vim support than that! I find it a god-send when working in VSCode as the Vim key map alternative was slow, buggy, didn’t have full support.
I actually battle vscode every freakin day over autocomplete. It's really bad if you're writing php and happen to have a // phpcs somewhere, it'll convert <?php to <?phpcs which makes no damn sense.
For my use case, autocomplete of any kind is useless, so I turn it all off. When "in the zone" anything that distracts from getting ideas out of my head as quickly as possible is annoying. Also, zen-mode, FTW.
Sometimes after I type a variable name (the whole word, not partial) it autocorrects it into something else. I am in the habit of hitting Esc after each word now.
edit: My only gripe with VSCode currently is that it seems too eager to correct my typing.
