Gantt chart more information left to chart than only a task title

[Gijs]

Hi all, 

I am currently missing in the Gantt chart a feature to add more information in front of the actual chart than only the title. Basically I would like to add multiple columns of information. 

Now we have task name and next to that the actual gantt chart visual. It would be great if we can add some custom columns of information. I would like to add e.g. the responsible party, type of work, ... I know we can add that all to the tooltip, but that is less of a clear overview than when we could add that as extra information in front of the visual,

Best regards,

Gijs
