Since OmniPlan does in fact support multiple projects (and a number of us have used it to manage multiple projects!), it helps to talk about what could be better about that support rather than whether or not they're supported at all.

What I'm hearing so far in this thread are two votes for easier ways to coordinate resource scheduling between multiple projects. (However, I'm not yet sure whether that's what the original poster is wanting to see improved. Sometimes when people ask about multiple projects, what they're wanting has nothing to do with shared resources at all—they just mean tabs in a window, or a common dashboard somewhere which lists active projects with their progress towards milestones, or a way to overlay multiple drafts of a project to see what's different between the two.)

Does that mean that you'd want each project to be able to participate in a single shared resource pool? What happens when you want to make another copy of the project to consider an alternate scenario? Do you make another copy of the "shared" resource pool as well? Or do you only publish to the pool when you've blessed a particular scenario? (In which case, how do you truly explore cross-product resource allocation scenarios?)

Now I recognize that it's not your job to figure out the answer to those questions—that's our job! But before we do that we do want to make sure we understand your needs so we don't design the wrong solutions for those needs.
