I have to agree with a lot of what the other posters are saying. To be able to link the Vibe tasks and milestones with a Gantt chart and visually present the project to stakeholders would be a real bonus.
I'm trying to push the project management abilities of Vibe with senior managers and project staff and the Gantt chart is the one that that is truly missing from nailing the sale.
For me it would be great if I can import project plan from excel as in our company most of plans are made in excel. Without Gantt char it is rather difficult to overview bigger projects.
