A few minor issues
This is a big improvement over the native SharePoint Gantt chart object.
I'm setting it up so that we can schedule scientific instruments for about 20 analysts.

It has an okay look when sorted.
It hides the base list and associated views so that you have to go through the Site Management to get to them.
It doesn't use the filter ordering, so I can't present it in an arbitrary initial state.
