Surprisingly, it's actually 50/50, the playerbase is split in half, so all of the suggestions matter to me. I'll try to implement hotkeys in the next release, though, there might be one visual problem due to the fact that unity's current input system does not allow for easy conversion of input key number to the UI, if someone chooses custom bindings, but. Default ones should probably work fine for the majority of people.
Thanks for the feedback, i am putting hotkeys into WIP now, i do appreciate communication a lot!
