Status bar
A status bar, aligned at the bottom of the screen, shows basic learning statistics. Additionally, it features a panel displaying hints related to an element in the SuperMemo user interface the cursor is currently positioned over. Note that you can also find the same statistics, along with many more, in the Statistics window.

You can show/hide the status bar with Window : Status bar available from the main menu.
Memorized panel
The first field shows Memorized/(Memorized+Pending). In other words, it shows what proportion of elements have already been memorized.
Outstanding panel
The second field shows (Outstanding items + Outstanding topics + Final drill items)/(today's original Outstanding). It illustrates how many outstanding elements scheduled for the current day have yet to be reviewed (the first two numbers connected with a plus sign) or have to be rehearsed yet with the final drill (the third number, if present). For example, (24+2+3)/45 means that out of 45 outstanding elements, 24 items and 2 topics yet have to be reviewed, while 3 items require additional review in final drill.
Note that whether the third final drill statistic is displayed depends on the Tools : Options : Learning : Skip final drill setting. When it is on/checked (i.e. the final drill is disabled), the number is no longer showed.
Outstanding progress bar
The progress bar displays the graphic representation of the same information as the second field. The blue color shows the proportion of elements passed successfully today (i.e. passed 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.
Hints/Basic element statistics panel
The right part of the status bar is used to display either:
- hints for elements in the SuperMemo interface (such as menu items, buttons, etc.), or
- the current element's basic statistical parameters.
The hints are displayed when Window : Hints is on/checked (you can easily notice that as they are showed against the yellow background). Otherwise, the panel shows the basic statistics for the current element: interval, priority, number of repetitions, and the dates of the last and next repetitions.
You can also double-click the panel to turn the hints on and off. Note that this is a collection setting. In other words, the hints may be on in one collection while off in the other depending on the value of this setting.
