Description

The extensions status bar widget changed considerably.

• Clicking it in its default state should open Quick Open with the text > Extensions: to display all extension related commands.
• It should report extension errors on startup with a decoration on its icon.
  • You can trigger an extension error by causing a syntax error in its package.json, for instance.
  • Clicking the widget then should display the errors and make the decoration go away.
  • You can only click it once.
• It should report extension updates with another decoration.
  • You can trigger this by editing an extension's package.json and rollback its version number as well as rename the folder in which it is installed (which contains the version).
  • Clicking the widget should display the outdated extensions.
  • This indicator never goes away while you have outdated extensions. It's a motivator to keep up to date.
  • The indicator should also update accordingly when installing/uninstalling extensions.
• It should report when extensions are being installed.
