New to TR, not new to GTD.

I have been using a few Mac based GTD apps over the past year. My trouble is that I have to live and work on Windows and Linux as well . . . so either an on-line solution or a multi-OS solution is what I need. I just cannot fall in love with the on-line options.
TR looks good.
Here is one initial question:
Is there a way to just view one project (and more importantly all its actions). There are times when I want to see all actions or all next actions . . . but there are times I want to just live in one project. Other apps have had this function and I have used it quite a bit.
