+          <h3>Android file system</h3>
+          <p>Due to the limited file system access on Android, all map formats that consist of
+          multiple files (eg. OziExplorer maps or World-file georeferenced images) will not load
+          properly when loaded from the application menu. You have to put such maps
+          to the GPXSee map directory to make them work.</p>

+          <h3>OpenGL</h3>
+          <p>There are numerous OpenGL issues in Qt that cause some kind of broken rendering
+          or even an application crash. OpenGL is thus disabled by default even if it can
+          significantly speed up rendering of big data sets. You may enable OpenGL in
+          the preferences, but be prepared that "strange things" may happen...</p>
