//! `bevy_feathers` is a collection of styled and themed widgets for building editors and
//! inspectors.
//!
//! The aesthetic choices made here are designed with a future Bevy Editor in mind,
//! but this crate is deliberately exposed to the public to allow the broader ecosystem to easily create
//! tooling for themselves and others that fits cohesively together.
//!
//! While it may be tempting to use this crate for your game's UI, it's deliberately not intended for that.
//! We've opted for a clean, functional style, and prioritized consistency over customization.
//! That said, if you like what you see, it can be a helpful learning tool.
//! Consider copying this code into your own project,
//! and refining the styles and abstractions provided to meet your needs.
//!
//! ## Warning: Experimental!
//! All that said, this crate is still experimental and unfinished!
//! It will change in breaking ways, and there will be both bugs and limitations.
//!
//! Please report issues, submit fixes and propose changes.
//! Thanks for stress-testing; let's build something better together.
