I would like to use a harness that integerates with an IDE very easily. This will be helpful for me when coding in a language I largely don't know. I can kinda check things quickly in front of me. I know it just needs an editor and maybe a language server setup – but the cost of visual context switching is still costly heavy for us humans. Often things out of sight are also out of mind.

I was aiming for VS Code but since I have used Intellij and android studio a lot maybe I'll give it a try.
