Not to speak for parent comment, but the reason I use vim plugins in JetBrains IDEs is to have all that shit "just work". Yeah, you can setup stuff to autogen tags, but it's not always reliable. If you care about other IDE features (I do) then the list of crap you need to do to get vim/nvim to work properly piles up endlessly. I'll take the IDE with it's nice appearance and features and slap the keybindings in any day over the reverse.

ctags (which is the way I used to do it) was always sort of hit or miss for me. JetBrains OTOH just works. Apparently there's a new way of doing it though, which I should look into.
