This iteration we have introduced the ability for quick pick items to have tooltips:

A make believe usecase of the Command Palette showing the extension that contributed the command

How to test

Prereqs

• If you're testing from an extension, pull in the proposed API:

  vscode/src/vscode-dts/vscode.proposed.quickPickItemTooltip.d.ts

  Line 14 in 0b89e36

  tooltip?: string | MarkdownString;

• If you're testing from Core, find a place in the code that already uses the IQuickInputService and just add some code there to play around with the API

For the Steps section below, I want you to try it out in both the "simple" and "complex" API:

• Simple in Core is the pick API
• Complex in Core is the createQuickPick API
• Simple in Ext is the vscode.window.showQuickPick API
• Complex in Ext is the vscode.window.createQuickPick API

Steps

Really just play around with the API AND the UX shown... but specifically test out:

• Does the API make sense?
• Does hovering over an item with your mouse show the tooltip?
• Does ctrl+space show the tooltip? - this works similarly to the suggest widget so try that out
• Add a markdown link in the tooltip. Can you tab over to it?

Have ideas of where this could be used? Open issues on that so we collect ideas!
