The status bar displays some information otherwise also available from the statistics window in a concise and graphic way.
The second field shows Outstanding/(maximum Outstanding). It illustrates how many outstanding elements scheduled for the current day have yet to be repeated (before the plus sign) or have to be rehearsed with the final drill (after the plus sign). The progress bar displays the same information in the graphic form. The blue color shows the proportion of elements passed successfully (i.e. with the grade Bright (5) or Good (4)). The red color shows the proportion of elements passed with the grade less than Good (4). And the white color shows the proportion of elements that have not yet been passed
The right part of the status bar is used to display hints for menu items, buttons, statistical parameters, etc. As you have probably noticed, this part becomes yellow as soon as the mouse pointer moves over a screen component such as button, menu item, etc. You can double click the hint display area to turn the hints on and off
