A global "Add" button on the upper right corner (in the header) to easily create new time entries, projects, tasks, notes and contacts.
This will be great! So we don't forget to add tasks and run time tracker.
A button to start the time tracker will be very useful. So we can start the tracker and after then add the details.
the buttons could be better seperated e.g. check vs. edit and buttons with estimated main functionality like "new" could be highlighted (like in google products)
