In #5396 we shipped an experiment to have DevTools embedded in the sidebar.

To try it out:

• Make sure you're on the latest version of the Dart extension (v3.108 or later)
• Add the following settings to your VS Code User Settings (or Workspace Settings to enable just for a single test project):

  "dart.experimentalSidebarDevTools": true, // Enables the functionality
  "dart.devToolsLocation": {                // Sets which sections should open in the sidebar (this sets everything except cpu-profiler, for example)
    "default": "sidebar",                   // Ignore the warning for this, "sidebar" is a hidden value so VS Code treats it as invalid
    "cpu-profiler": "external"
  },

• Restart VS Code (or at least run the "Reload Window" command to restart the extension host)

This issue is to discuss feedback about whether this works well enough that the experimental flag should be removed and ship it.
