-# Difference to [`egui-toast`](https://github.com/urholaukkarinen/egui-toast)
-### `egui-notify` has
- - Animations for appearing/disappearing toasts
- - Duration meter for expiring toasts
- - Toast positioning not influenced by which `Context` you pass to it (like if for example, you passed in a `Context` already altered for an `egui::Window`)
- - Differing methodology (create `Toasts` instance once, save save somewhere in application state)
- - Threadsafe `Toasts` instance, implements `Send`, `Sync`.
- - No support for custom toasts
