For me, I would love to see some other peoples Input Rules 
Tagging is all important in a Colour Managed Workflow and I have set my Rules up to get as many automatically as possible. I have just modified the default bunch you get with an ACES project but I have tried to make it catch as much of our material as possible.
The Pattern and Extension can be a little limiting and I would love to see this expanded to allow some knowledge of the folder structure files are found in. I have created a Feature Request if you agree with me
