The Statusbar gives you contextual help while hovering the mouse over different controls.
In addition, the statusbar will show warnings and error messages by expanding the statusbar for a few seconds, and then automatically hide it again.
The last error/warning you got is always available by clicking on the statusbar if you need to see it again.
All error messages and warnings can be 'turned off' by clicking the Statusbar and checking the 'Do not show this again' checkbox.
In the lower right corner you'll find the 'Tip of the day' icon. You may click this icon, or use the shortcut Alt+T.
