It would be nice to have "statistics by field" view for banknote collection too, not only for custom collectible. Additionally, is it possible to expand list of fields there? I want to see statistics by each field I use. Thanks. (Currently you provide only custom fields in the list; but in general not all common fields are present in statistics - add them also if it is possible). Also, it will be nice to leave “Full screen” mode using ESC button.

nice idea! I want same feature at least for custom fields...
