Tooling is definitely an area that needs much improvement. I prefer JetBrains IDEs over VSCode, but unfortunately the development of the current JetBrains [Nim plugin](https://plugins.jetbrains.com/plugin/15128-nim/versions) seems to have stagnated.
So I thought I'd try developing a new plugin, called [NimJet](https://github.com/khaledh/nimjet), but it's not easy. Nevertheless, I was able to get syntax highlighting working. I hope I can continue working on it for the next while.
