So as I see it, it basically boils down to resource allocation between several projects. This is indeed a severe limitation. Just adding a tab-feature does not solve this, I'm afraid.
Example: I have several customers with various projects each. So I set up a project for each customer and a task group for each project. After doing this, I have to balance my workload (I am the resource) manually. This can be a pain and certainly leads to a time delta, making predictions about the tasks' end quite difficult. But that is the question I get: "Will you get it done until the umptieth?"
