Not a question just a comment
You have managed to check off almost every single item on my task manager wish list:
1. Sync everywhere with everything
3. Great keyboard shortcuts
4. Calendar sync (surprisingly most apps don't see the point)
5. Apps for iOS AND Android
6. Natural language date entry
7. Email workflow
8. Last but not least great design
I tried todoist years ago and it just wasn't quite there yet, but OMG how you've grown! I saw a tweet about you yesterday, and had to check it out again and so glad I did.
I've used EVERYTHING... from Omnifocus to Toodledo, things, THL, Priorities, etc, but NONE of them hit the notes that you do.
Bravo, and please keep up the good work!
