Thanks for this!

Some quick notes:

It seems like to naming is inconsistent in the files. For example:figure.title_locy,figure.titleloc_y, andfigure.title_y are all used for what I believe is the same parameter. I think there needs to be some discussion about the "best" name. (Personally, I thinkfigure.title.y, but since there is, e.g.,figure.titlesize already, it doesn't really make sense to change format.)

This will also need a "What's new"-note.

Thanks for catching that. I settled for title_x and title_y as a good mix of both naming formats.

Standardized naming to title_ha and title_va
