A view of the inbox - just the projects with no tasks.

Selecting the "Calls" tag at the bottom of the screen.
Note how the projects that do not have visible actions are hidden,
simplifying your view. Items you have not changed in a while show up lighter.

Change the state of any action by clicking on the left-hand icon.

Expand any action to edit the note, start or end date, or the tags.

These are just a few of the features but you have to try it to feel the difference.
