Hi @Corna!
Thank you very much for your feedback.
First of all I wish you to know that I'm working on the next project - that will also deal with Global Warming, but at a much more detailed level. That's why I won't make big changes to EcoClicker from now on.
However I agree that your Ctrl+Click suggestion for bulk buy workers is a great one and is really quick for me to implement. I'll make this change in the coming days and update the game. Also if you have any suggestion for a research that would replace GMOs - or effect that GMOs has on the game - I absolutely might consider it!
Cheers!
