Milestones every 0 seconds just means that there are no milestones, and that is also the default. Use this for stuff in classrooms and all that. Can be set from 00:01 to 99:59.
*Not best suited if there are 100 or more milestones *NOT a Blocky Studio Production, but a remix Thanks to @MV42Channel for the original project This is like the original timer, except for the following changes: -You can start with a certain amount of time by clicking the "Start with custom time" button. -You can add milestones. -The timer will continue to beep 5 times. -You can reuse the timer without clicking the green flag again. -There is a progress bar (with the milestones marked of course) -Different background
