python-gantt's Issues

weekly resource view doesn't work

even if you set weekly, it shows you the resource view by day

unneeded extra row appears after milestones

For tasks, when a milestone is added, an extra row is added. This extra row doesn't provide any benefit. IMO, it should be removed.

weekly view doesn't show "this week"

It would be nice to have the same blue vertical line to show what the current time is for weekly view.
