Why did you change it to manual start? Normally it'd start when you opened a Leetcode problem page on its own. Now I forget to start the timer..

Works well. It has helped me solve a few hard questions which I wouldn't even have attempted before just because they were tagged as hard.

The latest update blurs the time instead of hiding it, its too distracting, please revert it back
