BMEGUY I also wanted some ToDo/Calendar/Alarm features, and was able to implement most of what I wanted through applescript. (Which I will try to make available on the developer site when I get all the bugs out.)
Now that the developer has included a user-modifiable framework (called Blocks) I'll be working to do the same thing but now in mac-native cocoa. In addition, the features planned for the next release of Mori sound exactly like what you would need, including "smarter" smart folders and user-definable column criteria.
I have a lot of confidence that this app will become a premier writing/planning solution.
