The standard tab that is opened from the Home session of the workspace is the Dashboard.

A dashboard can be configured with multiple views that users need for their day to day work. The space to view the lists/Views in a dashboard is limited.

It would be far easier for users to have the defined Views opening as default tabs on their Home session to avoid having to manually add them every time they start using the system. This would be in the same way that additional tabs can be configured to open when a new Case session is started.

It is much easier for a user to work with a complete screen view of their Cases etc rather than a small slice of the screen when using a dashboard that also needs a user to scroll up and down the dashboard.
