     activate a mode by either clicking on its mode selector, or using the
     \l{keyboard-shortcuts}{corresponding shortcut}. Certain actions also
     trigger a mode change, e.g., \gui{Debug}/\gui{Start Debugging} will switch
     to the \gui Debug mode.

     \section1 The Output Panes
 
-    The task pane in Qt Creator can display one out of four different panes:
-    Task List, Search Results, Application Output, and Compile Output. These

-    \section2 Task List
+    \section2 Build Issues
 
-    The Task List provides a list of important tasks such as error messages
-    that need to be fixed. It filters out irrelevant output from the compiler
-    and collects them in the form of tasks.
+    The {Build Issues} pane provides a list of issues, e.g., error messages or

-    The Search Results pane displays the results for global searches such as
-    searching within a current document, files on disk, or all projects.
-    In the screenshot below, we searched for all occurrences of \c{textfinder}
