I use timer presets quite often to manage lots of things. I like the fact that I can start timer for the most common intervals by using just several clicks. Before the update I had timers for 1, 2, 3, 5, 10, 15, 20, 30, 60, 180 minutes. After the update the last two timers just disappeared and I cannot create more.
Please return the old limit of 10 or, even better, increase it to 16 or more. I should make the timer functionality more user friendly.
