Will the use of hot keys be expanded compared to previous games? 

Amplitude games have a large number of pop-UPS that can be divided into several types. For example: the empty stage of construction; the choice of option in the event, etc. To increase the availability and convenience of users are not developers seldom assign buttons to different actions. 

What do you think about using hot keys in Amplitude games and how it could be developed in Humankind?

I recall Endless legend having a hotkey that allowed me to cycle through my units, Endless space 2 lacked this feature and forced me to have to use the icon on the lower right or manually browse my units list. Other then that I think it sufficient what they usually provide.
