+filtering, data sorting and data display.  All data is saved once and then you
+can display these data with custom filters, orders and styles.  The package
+can be used, for example, to record and display something you'd like to
+review, maybe the question you always answered incorrectly or some forgettable
+knowledge.  But obviously, the package is much more powerful and extensible
+for more interesting tasks depending on the individual.")
