These functionalities are most essential for HFT, and Machine Learning applied to HFT. If, even some of the methods, and functions will be added, it would improve the popularity of Zorro Project.
The screens look interesting. But I see no connection to HFT. They appear only to visualize the order book. This is useful for manual trading, but for automated trading you have already access to the order book.
