1/ Controversial take: hard work is more important than smart work.
It's a myth that we only have a few hours of good creative work per day. Train yourself to grind long hours first. You will surprise yourself. The work naturally become higher quality, less distracted.
Published the extension source code on github so you can review the code and know exactly what you're downloading from the chrome extension.
You can test the extension locally through developer mode on chrome:
1. Go to chrome://extensions
2. Find the toggle switch labeled Developer mode in the top-right corner of the page and turn it ON.
3. Clone the repo to your desktop and click on load unpacked on chrome://extensions.
4. Test the extension.
Features may be limited due to some of the keys in the repo being placeholders. For obvious reasons we cannot expose our keys.
Idea is that you can test and audit the code for the extension and then decide whether you'd like to download the chrome extension.
Full transparency.
