 <h2>NOTES</h2>
+Some operations (copying, renaming, deleting) are by default enabled only within the current mapset.
+To allow changing data outside of your current mapset, you need to press <em>Unlock</em> button in Data Catalog toolbar.
 
 <h3>WARNING</h3>
+When renaming, copying or deleting maps outside of Data Catalog, you need to reload
+the current mapset or entire database, because it is currently not synchronised.
