I have soooo many features in Neovim, and passed the first two days I stopped missing them a lot.

Very frequently (<10m)

finding files in vim: I bind to an fzf thing in Neovim and it’s great. Unfortunately vim doesn’t have anything like that built-in.
<leader>w/b/etc to move forward camel-cased
Syntax highlighting sucks
- import { type foo } in TypeScript breaks the whole file
Can't find the types of things
vim-tmux-movement
Need to save files before editing new files
can't open files like src/utils/helper.ts:369:14. lervag/file-line does this

bash history splitting multi-line commands into different history entries
completions for git and yarn
jump for zsh
control+p for finding files in zsh
my aliases
my shell functions
not being able to open the command I’m writing in a vim buffer. I used this a lot with zsh, but want it even more now since editing bash is harder

Frequently (<1h)

These are the things I find myself missing ALL the time (multiple times every ten minutes).

There are other things that I miss at least once an hour:

LSP stuff
- I reflexively hit gd at one point and my mind was blown when it worked. I forgot vim does a pretty good job at figuring this out from syntax alone! If not for this “not having goto definition” would have been in the “very frequent” category
- Figuring out if my code has errors sucks. Would be a lot less bad if my build times were fast, but since they're slow AF my feedback loops take a long time
Way better syntax highlighting
- fewer languages support out of the box
  - graphql
Maybe just because I’m so used to nvim, but I’m used to my cursor changing shape depending on mode and not having that in vim makes me get confused sometimes
vim-surround
copy/pasting to/from system clipboard is annoying. Forget to say "+y"
files auto-reload when edited elsewhere

zsh will guess-complete tab-completions. For example, if I have directories ce-smartlists, ce-fart then in zsh if I type cd smart<tab> it will autocomplete `cd ce-smartlists
case-insensitive tab completion
