I am a long time JetBrains user - have been using it for the majority of my development over the past couple of years. I have recently delved into Cardano development, which is built on Haskell. I have tried other IDEs for Haskell and they definitely leave something to be desired (Emacs, VSCode). Definitely pining for the precision and reliability of JetBrains. I have tried the Haskell Plugin with a basic Haskell stack project, but even basic functionality like syntax highlighting and Go to Definition doesn't work very well.
I think the effort will ingratiate you to a growing and important developer community!
