It would be great to have more control over a Quickpick. Here are some things I would love to have.

1. Stream or push items into a Quickpick (basically be able to show/add more items to the list as promises are resolved)
2. Update the placeholder dynamically
3. Control which item should be selected when shown
4. Add event for right-arrow press on an item, similar to the file access quickpick
5. Seed the inputbox with a value
