IntelliJ is my daily driver, but I mostly stuck to VSCode for Nim because of better support although I otherwise loathe it. Nimatron was a good effort and progress was coming along nicely, but the developer retired it when Jetbrains released their plugin. Still, big props to the developer for his work on it.
The new Nim plugin is a good start. It's not feature complete - it lacks some things like jumping to definitions in other files, and commenting out the highlighted lines with a keyboard shortcut. It's not as good as VSCode's plugin, but it's mostly good enough to start using Jetbrains for Nim development. The real worry is that 1) it is just some [Jetbrains developer's 20% project](https://youtrack.jetbrains.com/issue/NIM-2#focus=Comments-27-4201447.0-0), 2) since JB is now developing it, it is closed source and no one else can contribute or pick up the slack if the developer loses interest or moves on (as opposed to Nimatron).
