 ## Features
 
-Inspired by [Xilem](https://github.com/linebender/xilem), [Leptos](https://github.com/leptos-rs/leptos) and [rui](https://github.com/audulus/rui), Floem aims to be a high performance declarative UI library requiring minimal user effort.
+Inspired by [Xilem](https://github.com/linebender/xilem), [Leptos](https://github.com/leptos-rs/leptos) and [rui](https://github.com/audulus/rui), Floem aims to be a high performance declarative UI library with a highly ergonomic API.
 
-- **Cross-platform support**: Supports Windows, macOS and Linux with rendering using [wgpu](https://github.com/gfx-rs/wgpu). In case a GPU is unavailable, a CPU renderer powered by [tiny-skia](https://github.com/RazrFalcon/tiny-skia) will be used.
+- **Cross-platform**: Floem supports Windows, macOS and Linux with rendering using [wgpu](https://github.com/gfx-rs/wgpu). In case a GPU is unavailable, a CPU renderer powered by [tiny-skia](https://github.com/RazrFalcon/tiny-skia) will be used.
 - **Fine-grained reactivity**: The entire library is built around reactive primitives inspired by [leptos_reactive](https://crates.io/crates/leptos_reactive). The reactive "signals" allow you to keep your UI up-to-date with minimal effort, all while maintaining very high performance.
-- **Performance**: The view tree is only run once, safeguarding you from accidentally creating a bottleneck in a view generation function that slows down your entire application. Floem also provides tools to help you write efficient UI code, such as a [virtual list](https://github.com/lapce/floem/tree/main/examples/virtual_list).
-- **Flexbox layout**: Using [Taffy](https://crates.io/crates/taffy), the library provides the Flexbox (or Grid) layout system, which can be applied to any View node.
-- **Customizable widgets**: Don't want the default look? You can change pretty much anything you want using the styling API, or install a third-party theme.
-- **Element inspector**: Inspired by your browser's developer tools, Floem provides a [diagnostic tool](https://lapce.dev/floem/floem/id/struct.Id.html#method.inspect) to debug your layout.

+- **Customizable widgets**: Widgets are highly customizable. You can customize both the appearance and behavior of widgets using the styling API, which supports theming with classes. You can also install third-party themes.
+- **Transitions and Animations**: Floem supports both transitions and animations. Transitions, like css transitions, can animate any property that can be interpolated and can be applied alongside other styles, including in classes. 
+        Floem also supports full keyframe animations that build on the ergonomics of the style system. In both transitions and animations, Floem supports easing with spring functions.

 To sample Floem's capabilities, check out the repo and run the [widget gallery](examples/widget-gallery/src/main.rs) example with cargo.
