Usage:

run the /quality-upgrade-planner command to get a book that has a page for each quality,
dragging that book over an area will request an upgrade of everything selected to that tier.

Planned features:

• less bizzare thumbnail
• a shortcut button, so you don't have to run the command every time
• caching the item in a script inventory and merely giving a copy when triggered
• supporting quality that is out of order, contact me if you know of a mod that breaks this one
