|To remove unwanted tabs (top nav) on your start screen simply do the following:
1. From the designer, browse to the Themes Directory.
2. Then find the "template.view" it will bring up the start page Main navigation.
3. Then simply select the unwanted tabs, and press your delete key.
This is helpful, when you create tables, as they will all show up on the main template, and you may not want all the tables to show up there.
