WRP,
You're fighting a losing battle here. I understand completely where you're coming from. FCP has had feathering capabilities for each clip without adding an additional effect since as far back as I can remember. Apple, for whatever reason, pulled it from FCP X.
The fact that the "solution" is to buy Motion, build the effect you want and send that effect to FCP X is ridiculous for something this basic. It might be an effect in Avid, but again, it's a basic effect and it's included, ready to use.
I have a love/hate relationship with X. I've been fooling around with it, and finding a lot of nice things... then I hit the one bad thing-- a basic feature that missing or a feature that isn't working correctly-- and I want to put my head through the monitor.
The biggest frustration for me is the fact that in the viewer/canvas/whatever window, there is no visual indication that you set an I/O point on a particular clip except for the yellow selection bar thingy in the events panel. So infuriating when you're on a dual monitor and you keep having to bounce from one screen to the next to see if you set an I/O point.
