You can use UI Library to show more formatted information with nicer fonts without having to add a template to your Shortcut each time, or to show a Markdown/html table. Or to choose a Shortcut(with Search), choose a color, easily show a list of percentages, or a list with images in the menu by passing an image, or with no images, by just using a name of a pre-loaded font awesome icon.
All of these are done with 2/3 actions added to your Shortcut. A dictionary with the details, a Run Shortcut action, and sometimes a text action.
For example to show percentage bars like thisYou just need to add this to your Shortcut.
To show a list with imagesJust send this across to the Library.
