Would like the ability to enhancing the GANTT view to show colors and labels for groupings. Right now, a grouping shows up as a single color bar, with no details on the breakdown of components. If this grouping could show colors from these components and details in the group's bar, that would be super helpful when looking at many collapsed groupings across many projects.

In the 4 screenshots below, observe how the GANTT view with the disclosure open will show each item, but when closed there's just a block even when the items sequentially stack, so all I see is a big block of turquoise instead of a sum of the parts.

In contrast, the timeline view has this ability, and it's handled in two ways:

-when the items are show sequentially, the color blocks fit across the span.

-when the items have some overlap, the row dynamically grows for the overlapping time.

So, the Timeline view offers a good example of how the collapsed GANTT could be more useful :)
