Countdown timer for pomodoro

[tonyxiao]

💻 Environment

Platform: macOS

📒 Description

While Pomodoro mode is active, instead of showing time elapsed, show amount of time remaining.

⭐️ Why do you want this?

This avoids doing mental math of 25 (or whatever I happen to have the Pomodoro Timer setting to be at) minus currently elapsed time to know how much time is remaining. It really helps with focus and staying alert.
