I've made the same request to Omni before. Hopefully the more requests made, the sooner this will be implemented.

One note that might be helpful: You mentioned:

"Some indication / warning that you just checked off the last action in a project as 'done'"

I use the OF iPhone app exclusively (don't have a Mac), so I sorta accomplish this by making my last task in a project always have the action title !!!!

This way, if I see !!!! tasks in my context lists, I know that I've completed a project (or need to go back and add additional actions). I can also search for !!!! to get a quick list of stale projects
