Hi Rafael,

I share Aaron's concerns regarding an overcomplication of the interface.

I hope I don't miss anything important, but:
Wouldn't an efficient and elegant interface contain only two options? 
Firstly the default: "Show all files" and secondly: "Show only a subset 
of files". The second option then contains a lineedit in which a user 
can write his filtering criteria. Below the lineedit you present one or 
two examples of how a filter is constructed:
Show only PDF files, that do not contain "university" in the filename -> 
isType:PDF !university
A tooltip is needed to provide the user with a short introduction to the 
syntax (see Amarok's OSD creator). Furthermore this filter needs to be 
available throughout the desktop experience, i.e. dolphin should honor 
the syntax too.

I think this would be a visually minimal interface that scales well with 
various experience levels of users.

Just my two cents.
