Really well done the design is beautiful, but to be really useful you need to easily find a way to display the information like this table [1]. I felt like i had to keep moving the bar and I could not quickly get the best time needed.

Really nice! Very clean design, and I really appreciate the details and finish; drag and drop reorder, the time diff based on selection, the reset button after changing time, subtle colon "second" animation on current time. Well done!

Very nice, I’ll be using this
