How can I change the title of my default contact and event file? Also, where is the default located?
The name shown at the top of the window is the name of the selected tab. For the next release we've changed the default name of new tabs to be 'Untitled Tab' to give a little more help in figuring out what's untitled.
To change the name of a tab, double click on the text in the tab, and it will allow you to edit it. Changing that name will then change the title of the window as well.
