I'm reinventing the wheel and creating a day-view calendar within my WPF app to facilitate making customer appointments. I'm basing my design off Google Calendar and Outlook. I noticed that both of these calendars allow you to add appointments by clicking on the calendar itself and also via a "Create/Add" button in a toolbar.
I'd like to know people's opinions on whether I can get away with just using the click on the calendar method (a soft modal)? I personally find that I very rarely use the toolbar method when I'm using Google Calendar. Also, my app will not need the same level of features as Google Calendar/Outlook which makes a large modal dialog hard to justify. Implementing both methods seems like unnecessary work to me.
