OK, that sounds good enough to me. If I understand the solution
correctly, there will not need to be any changes to the file format for
example, since only the already existant fields will be used (fixed date
+ priority).

By the way, would it be possible to split the patch into the drawing
parts for non-working time and the rest? It's going to be a pretty big
patch so that would help a lot.
