[Feature Request] A basic Pomodoro timer as a widget

[valdrin888]

Hello,

First of all, this extension is by far my favorite new tab page now. I'd like to thank you all contributors for maintaining this.

This request is not a must-have one but I think it would be a good addition to this. While I was checking the widgets, I've thought "there should be a timer as well", maybe a basic Pomodoro widget which has start/pause/stop toggles, custom values for work/small break/long break timers, etc.
