You can also set the default tab within individual projects - click on the Manage Tabs icon:
After clicking on the tab, you'll see a screen listing all the available tabs. Select Hierarchy, save and return.
Two notes:
- your IE settings and local cache may not reflect the change right away- you may need to log out/login or hit F5 to see the change
- also, some links are 'hard coded' to take you to a particular page; for instance, the 'properties' icon is usually set to take you to the project's properties page, regardless of your default tab settings.
The latter point can vary based on customers configuration changes to Clarity. We try to always have the 'properties' icon take one to the properties page, regardless of object type (i.e. on project list view, click on properties icon and one sees project properties page; on issue list view, click on properties icon and see issue properties page; etc.). Then, we try to always have the name field linked to the default tab setting. One should always expect consistent result - click on properties icon, see properties; click on name, see default tab.
