I find this feature extremely useful. I find myself looking for ways to pass the time. When I have CAPS engaged for specific reasons and the blue button pops up, it takes time for me to move my cursor around in an attempt to avoid it. When I fail, accidentally click it and must go back to hit CAPS LOCK again, I have spent additional time. And! the whole issue repeats once I click CAPS LOCK again. It is a delightful feature that only I find useful as someone who just wants the inevitable march of death to approach as quickly as possible while I fritter away at mundane tasks. I understand that the other 799,999,999 people on Earth find this feature completely useless and unhelpful, but I believe Apple did this... Just. For. ME! Thank you Apple!
