I don’t have a scroll wheel. I will never have a scroll wheel. (because I can’t - don’t ask…)
Why would anyone design a UI that requires a scroll wheel? PLEASE fix the UI so that those of us without a scroll wheel can get at all of our colors! Otherwise my beautiful Glowforge is unusable!
I agree that there should not be a requirement for a scroll wheel and I hope they fix this for you but I have learned that we never know how long something like this will be so I always think of how to overcome first.
Can you reduce the number of colors?
Can you install a scroll wheel emulator?
If you have a third mouse button you may be able to set the third mouse button to scroll when held. Other mouse software may allow both buttons held together. This does seem to be an oversight!
