Add shortcuts to icon/button tooltips
Todoist is amazing in its keyboard friendliness, but one thing that could make it even better is adding shortcut information where available to the icon and button tooltips.
This is similar to the way it is done in many other applications such as Photoshop, Illustrator, Visual Studio -- you name it! People start using the application, click on the buttons, and discover faster way of doing it all while doing it, without a need to dig through help pages.
Just a thought...
