Feature Request - Add a popup timer to show the duration spent on the website (see the screenshot attached)

[ms-2525]

Current we can see the time in the extension icon. I like to keep all the extensions hidden and so can you pls add a time like small widget on the webpage itself in the top/bottom left/right position. I am attaching a screenshot to illustrate the timer

I'd like to see this feature.

Plus another option to show how much time is left "if" the site has been put under the "limit" option.

So a countdown before it locks out. And a notification feature every 5mins, as a reminder.

Thanks
