With the new 30 minute increments you can now plan your resource bookings in half-hour gaps as opposed to full-hour. This new time setting also allows you to schedule your working day to start or finish on a half-hour which will help those businesses who have a working day which ends at 17:30 for example.
If you would like to see a more granular day-view grid you will also be able to adjust your grid to display half hour intervals by visiting the settings page under Account Settings.
Thank you for all the feedback on our suggestion forum.
