 Known Issues
 ============
 
-Combo Box
----------
+Dialog style
+------------
 
-Describe the problem, add some images and code.
+Dialogs, e.g. file dialogs, could appear not styled since it inherits from OS
+theme/style as described in the issue
+`#172 <https://github.com/ColinDuquesnoy/QDarkStyleSheet/issues/172>`__.
+There are some options that can be exploited there.
+
+
+System icons
+------------
+
+Similar to the Dialogs, default icons are inherited from OS but we
+are planning to create our own set of icons to provide a more uniform UI. See
+`#192 <https://github.com/ColinDuquesnoy/QDarkStyleSheet/issues/192>`__.
