Presentation Pacemaker

In order to keep your presentation in pace, this chrome extension shows icons one indicates the progress of time and another indicates the progress of your slide. You can easily see where your presentation is too fast or too slow.
Heavily inspired by the presentation tool 'Rabbit'(https://rabbit-shocker.org/en/).

Supported slide sites:
- Qiita(qiita.com)
- Google Slides(fullscreen mode)

Toolbar button will be activated when you're in these sites, and entering the duration of your presentation(in minutes) starts the timer.
