Interesting. There are a few products out there. I'll wait and see if this one works for me. Looks promising.

Meanwhile, I have trouble getting Google Calendar integration to work:
"You are almost done! Paste this authentication code in Subtletab customization menu"
Where is this menu???

NVM. Just found it. You probably should say: (Bottom left) Customize --> Clock
And why is it under Clock? Nothing about Google Calendar hints at clock for me. Either Todo or its own tab would work better.

Even though this extension controls my homepage and new tab page it doesn't load the first time i start the browser. Otherwise like it a lot!

Exactly what I was looking for. I love having a nice customizable desktop when I open a tab. I keep one tab open on my 3rd monitor at work all day as a sort of dashboard with my Todoist tasks. Side note, I would be willing to pay for a PRO version that had add-ons. It would be great if you could have multiple widgets on the desktop (ie. Notes and ToDo, plus maybe even controls for Spotify or other widgets). Or even to select a custom filter for my Todoist list, instead of only the Inbox. Could be a great revenue stream. I'm sure I'm not the only one that would pay for more features. Keep up the good work!
