I wish you well.
In my humble opinion, please feedback below to management to max your $$$ for your pleasures, family's benefits & charity.
Problem: BetterTouch Mac Tool: Need to look at keyboard to execute function = waste time. Why? E.g CMD + Left Mouse Click to execute Mac Screenshot of CMD+SHIFT+4.
Although intermediate to expert users know how to press on CMD key without looking at keyboard - It will be helpful to everyone including beginners if the spacebar key could be used as a modifier key in future = "Spacebar"+Left Mouse Click = Screenshot.
Why? Surface area for spacebar key is the largest = easiest to press = less mental load to think and find keys compared to smaller keys = efficiency & effectiveness.
Why not delegate this fix as a new project max your $$$?
Imagine what is the value of this feedback for you, your future generations and your circle of influence's current & future businesses lifespan.
