We are finalizing the shape of the tabs API and want feedback alongside bug testing .

• Create an extension using this guide
• Add the proposed API:
  • First add the proposed API to the package.json (see below)
  • Then run npx vscode-dts dev to get the typings

	"enabledApiProposals": [
		"tabs"
	],

Some things to test

• All the functions work as expected
• Names and comments make sense
• API feels easy to use and there are no major pain points

Additionally any general feedback regarding the API is greatly appreciated.!

If someone has the energy: would be nice to validate the API with an extension sample (https://github.com/microsoft/vscode-extension-samples), e.g. a custom tree view that re-implements the "Open Editors" view.

I could go on with testing because the API is quite complex and there are a lot of corner cases.

@bpasero Thanks for the testing :). I'll suggest it to Kai and SteVen as a possible candidate for the sample I do next iteration
