State of Haskell editor/IDE support

This chart describes the support level of each Haskell editor/IDE plug-in combination.

In most cases there is a main plug-in which acts as a base for the provided features.

Each known plug-in has an associated link and tooltip with its name.

🌱	Immature, only for early-adopters
🥈	Mature, suitable for most programmers
🏆	The best™ possible experience

Notes:

native support (probably minimal)
via main plug-in
this plug-in needs special config and/or system deps, refer to its documentation

Backend - The engine which makes some processing behind scenes to make most of the features available
Easy to install - Is this setup easy to reproduce? Better when it is one-click and it just works, less when it needs special config, compile by hand, etc
Syntax highlight
Code Completion
Error Reporting
Lint
Code Format
Goto Def
Find Usages
Stepwise Debugger
Doc. tooltips
Snippets - Predefined and customizable templates for pieces of code you write often. For example, if you write case, an editor might provide a completion like
```
case ___ of
  __ -> ___
```
Hoogle
REPL Integration - Be able to load/reload a file to e.g. ghci and provide interaction. Autocompletion and syntax highlighting are also welcomed.
Build Command - Project compilation cycle can be started using the editor preferred way
