Firstly, great tool!!

The one thing holding us back is that you do not address a very required feature of any PMM tool: Resource Management.

The various reports you offer are great, but they do not show a PM what they need to see:

1) When am I out of available resources

2) What can I move or delay in my Gantt view to rebalance the workload per task.

Here are some examples or really great resource management we have seen:

TeamGantt: Perfect example of gantt and load

MeisterPlan: Love how projects can be ranked and then tasks layers per resource.
