This is also one of my main concerns with OF as of today. The problem goes deeper still though. I would go as far as to say that OF currently does not support sub projects!

You must not think of action groups as sub projects. They are not!
They are simply a collection of actions within a project. It allows you to structure things better in planning mode and they allow you to have a combination of parallell and sequental tasks within a project. But they are NOT sub projects.

They cannot be reviewed on their own. This is a major problem if you have large projects that contain many sub projects (possibly also large) that you might want to deal with separately or even assign to other people. They also cannot be put on hold or dropped on their own.

I.m.o, Omni should do something about this problem before anything else...
