I hope it does work and improves the UX.

Shouldn't the description of this PR or some other documentation changes describe how one is supposed to develop with enso.dev.insight? E.g. that automatic reload is now on?

[4e6]

Yes, the reloading is always enabled. For now, it should be ok because the property should be used only for development purposes

[JaroslavTulach]

I am experimenting with Detect Assign Statements "useful" script. E.g.

• store the script into in.js
• launch project-manager as ENSO_JVM_OPTS=-Denso.dev.insight=pwd/in.js sbt --java-home ~/bin/graalvm/ runProjectManagerDistribution
• launching IDE in another terminal as corepack pnpm run dev:gui
• opening in.js in an editor

Whenever I alter the script, the changes are picked immediately up as soon as any Enso code is re-executed. Great work!

The next step is to expose Y.doc server structures (e.g. especially the node.js emulation) to this Enso Insight script.
