Todo shouldn't be just one line! I am constantly frustrated by having only one line of Todos to write. Finally, I merged Todo and Note and created the product Todo Note. You can write a Todo like Note without being limited to one line. Of course, you can also add tags to it. I personally recommend adding emoji to the tag to increase the fun. Get started using it, I hope you'll love it.
