You will need to install a user script manager extension to install this script.
Have you ever had a hit expire on you because you forgot it or lost track of time during a survey? This script will warn you when your time is running out. There are 3 ways it will warn you. First one is by voice and can be changed to a male or female voice. Second way is to have an alarm sound. Third way is to have the colors change around the hit window. You can't have voice and alarm on at the same time but you can have the color work with the sounds or work with no sound. The warnings are on by default at 30 minutes, 5 minutes, 1 minute and 30 seconds. You can turn on warnings at 10 minutes, 20 minutes and 1 hour also. You can also turn off the warnings if it's too much. It is smart enough to not warn you when you just started a 10 minute hit. It will warn you at the next warning time left. I tried to make the colors cooler when you have a lot of time left but make it unique while the time is counting down. Under 5 minutes the colors turn closer to red. There is also a volume control now which can be used but will not be saved at this time.
This script is still in beta so can't guarantee it will work perfectly so keep checking that timer.
