Big thanks for these ideas, i want to explain some:
I will add all subtitles, and option for it in "options menu". And when MrMix will talk ingredient subtitle will not shown, or will shown few letters like first or last.
Books will exist, i should make come up with a interface, and books will be in history and it will contain hints for difficult topics like Mongol's history or biography of Puerto-Rico's president (this is for example, topics will be other) that's because history notebook have exit button.
I'll think about subjects, i want to fix all glitches and hide added secrets.
Write if i miss something.
