# Objective This PR introduces Bevy Feathers, an opinionated widget toolkit and theming system intended for use by the Bevy Editor, World Inspector, and other tools. The `bevy_feathers` crate is incomplete and hidden behind an experimental feature flag. The API is going to change significantly before release. --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>
