Rich Text Editing
Previously, styles could only be applied to the text field as a whole. With the new WYSIWYG editor, you can edit text like you would on Google Docs or elsewhere, applying styles to individually selected sections.
The bigger change that this enables is the ability to insert properties into text fields. Whenever you type @, the text field will pull up a menu with a list of properties that you can insert. This allows embedding properties inside a larger body of text.
For example, you could have the text +4 actions on a card where the number 4 comes from a property.
