New pipe that would sort things based on Forge's ore dictionary, for example if I put wooden log in blue filter, all kinds of wooden logs would go in blue output.

I like this idea.
Perhaps it could be done by adding either a second diamond pipe. Or adding a button to the GUI which would allow to toggle this feature?

Probably interesting: A fuzzy sorting mechanism that could be somehow configurable.
For example, one could filter all logs to one output, all food items to another and all types of tools and weapons to another one.

I don't know whether this is also possible with the ore dictionary.

I already working on something like that. So no request needed.
