-In order of priority:
-- Write [[#chap:intro]].
-- Write [[#chap:discussion]].
-- Finish chapter [[#chap:feedback]].
-  - Add some screenshots to the start.
-  - Make sure there isn't too much overlap with\nbsp{}[[#subsec:whateval]].
-- Write [[#chap:summ]].
-- Redo screenshots/visualizations.
-  I might even wait with this explicitly to do this closer to the deadline, to incorporate possible UI changes that might be done in the near future.
+In volgorde van prioriteit:
+- [[#chap:intro]] schrijven.
+- [[#chap:discussion]] schrijven.
