This iteration, we introduced a new proposed quick pick API... Buttons on QuickPick Items!

definition:

        // extends what is in vscode.d.ts
	export interface QuickPickItem {
		buttons?: QuickInputButton[];
	}
        // extends what is in vscode.d.ts
	export interface QuickPick<T extends QuickPickItem> extends QuickInput {
		readonly onDidTriggerItemButton: Event<QuickPickItemButtonEvent<T>>;
	}
	export interface QuickPickItemButtonEvent<T extends QuickPickItem> {
		button: QuickInputButton;
		item: T;
	}

Please play around with this API addition and let me know what you think. Keep in mind, you may see this issue: #109969
Use keepScrollPosition property on the QuickPick to help with this.

Full steps if you need them:

• create an extension https://code.visualstudio.com/api/get-started/your-first-extension
• then run npx vscode-dts main in the root of the extension repo to get the latest vscode.d.ts API typings
• look at quick pick examples here: https://github.com/microsoft/vscode-extension-samples/blob/main/quickinput-sample/src/quickOpen.ts#L53

these buttons are only supported on the window.createQuickPick object and not on the simpler showQuickPick

Useful stuff

• Create an extension guide
• Extensions samples repo
• Add a finalized API: npx vscode-dts main
• Add a proposed API:
  • First add the proposed API to the package.json (see below)
  • Then run npx vscode-dts dev to get the typings

	"enabledApiProposals": [
		"quickPickSeparators"
	],

Note the name of the proposed API is gathered from the file name in the vscode-dts folder

All works nicely! Looks like this is now already in vscode.d.ts, so I guess "enabledApiProposals": [: [ "quickPickSeparators" ] is not necessary.
