Minor comment to avoid possible misunderstandings: Version 2.4 still has the "text graphical" hours output format available. It has however been renamed from -h / --hours to -hg / --hoursgraph. This was done in order to have the output formats of -5 / -h / -d / -m / -y / -t share the same list style format and be more consistent as a result.
