Their ideavim plugin is pretty good. I didn't know at first, but it support an .ideavimrc file that allows you to set your own commands. Pretty much anything that you can do in a jetbrains product is connected to a command id that you can connect to a vim shortcut.

Include the most popular vim plugins as well. Easy motion and Nerdtree. Doesn't support language specific plugins, but core jetbrains products covers that

I do the same (not for golang tho). However, vim plug-ins also "have network access", in fact they can just "system()" and call anything. No sandboxing at all. At least the source code of these plug-ins are not obfuscated/compressed.

However, this makes me wonder how much of a surface attack this is.

Do you pin your plugins down to commit hash?

I did in the past.

Now I just run `:PlugUpdate` and hope that whatever comes from GitHub, is seen by the manyeyeballs. I certainly don't check all the diffs.

Did you try IdeaVim?
