Nice idea! I have been interested in incorporating saved searches in my system for a while, but have not yet decided to implement it.
I recognize that the way I handle the inbox is somewhat redundant, but works for me. I can see that the method you propose may be a good answer and may implement it when I get to the saved searches.
As for Gcal… I am turning blue in the face waiting for someone to connect Google Calendar and Evernote. The APIs are there… it can be done!
…If only I knew how to code well enough to do it. :P
