Crate ftui_extras 

Optional feature-gated extensions for FrankenTUI.

Each module is behind a Cargo feature flag and can be enabled independently. These modules provide higher-level functionality built on top of the core ftui crates (render, style, text, widgets).

Role in FrankenTUI

ftui-extras collects optional, higher-level utilities that are useful across apps but not required by the core runtime or render kernel. It is feature-gated to keep the base dependency graph lean.

How it fits in the system

Extras build on ftui-render, ftui-style, ftui-text, and ftui-widgets. You can enable only the pieces you need without pulling in everything else.
