It seems like the only features OmniFidget needs are:
1. Read potential actions from a perspective. That way you can set up whatever subset of actions you'd like to fidget on. Since I'm a programmer I have basically one big context: Internet. However, sometimes I'd like to knock out Work Project actions and sometimes I'd like to knock out Home Projects.
2. Display more information about the task. In fact, you could read that from the perspective too. That way I can "No" actions that take longer than I'd like to fidget for.
BTW, I have been dreaming of just such a tool! Great job! If someone on the Omni team implements these two features, I will personally take them out for a drink (or offer them a free lunch at Google). I work in Seattle. :)
