Update the chart in real time as other users modify it
We've been using the tool during project planning meetings, where several users have the chart open and modify it as new tasks are created. However, the chart isn't updated until a user refreshes the page, or makes some other change. It'd be great to have the chart update for everyone as soon as the change gets made!
...The fact that I had to refresh the suggestions page to see my vote applied to this suggestion.
In the same line of thoughts, we would like to see who else is online and updating the chart...
