- Type information and documentation on hover. Note that currently, in order for docs to be displayed for dependencies, they must have been built with GHC's `-haddock` flag:

- For cabal:
- Add to your global config file (e.g. `~/.cabal/config`):
```
program-default-options
ghc-options: -haddock
```
- Or, for a single project, run `cabal configure --ghc-options=-haddock`

- For stack, add to global `$STACK_ROOT\config.yaml`, or project's `stack.yaml`:
```
ghc-options:
"$everything": -haddock
```

This will cause compilation errors if a dependency contains invalid Haddock markup, though in a future version of GHC (hopefully 8.12), [these will be demoted to warnings](https://gitlab.haskell.org/ghc/ghc/-/merge_requests/2377).

- Many more (TBD)
