Command Palette: ability to order results e.g most recent

### Description of the new feature / enhancement

when using the command palette it would be useful to have the ability to sort the results e.g. by last used, name

### Scenario when this would be used?

all

### Supporting information

none. Just my thoughts

Start by locating the Command Palette implementation and how it currently orders results. Define the supported ordering options, such as last used and name, then verify the selected ordering in the Command Palette.
