Amazing... But can you design another?

I bought this timer for teaching my yoga classes. The countdown timer is great because it gives me visual cues when I need to start wrapping up the different elements. But also lets me know that I still have 20 minutes left too! Now it would be great if you could make a fifth timer that is an interval one. Nothing complicated. It would be great to have a timer to exercise to. (ex. 5 min run 1 min rest. OR 2 minute reps. Etc). Im sure I could find other uses for an interval type timer but I cant seem to find a simple one out there. And why should i buy five different timers for my life? Thank you!!
