Unless you are running it on your microwave's microcontroller, it's not going to be slow. *That being said*, it should be expected to run at decent speed on raspbery pi-level hardware.
 * **Multi-threaded UI.** Callback methods are blocking - careful what you're doing in there! Feel free to use threads on your side, though.
-* **Complete ncurses equivalent.** You _can_ access the underlying ncurses window when creating your own custom views, so you can do what you want with that, but the main library will probably only use a subset of the ncurses features.

Also, using ncurses at all is not guaranteed, [as other backends are considered](https://github.com/gyscos/Cursive/issues/34).
