when looking at some failing unit tests I noticed that some code has been 
commented out with the comment FIXME when preparing the branch.
There was one FIXME for stage but there are still quite some for sheets and 
plan.
I miss the knowledge to work on those so maybe the maintainers should take a 
look and fix them.
