+1 for feature request of an exclude subgroups option from classify. Here’s the use case, I am a lawyer and I set up a top-level group for each client. I think classify works best when limited to top level groups. When I’m sorting through a 1000 or more PDFs in rapid fire filing mode using classify, I like to keep it simple. But I often get what what lawyers call “discovery,” which isn’t organized in this fashion. For example, I might get an extraction of my client’s cell phone taken from the police, and I will drop that in my top level client group. Now the problem is I have this cell phone filesystem download that may have 1000s of subgroups in it that are essentially meaningless to me but pops up in my classify pane, slowing me down. In all fairness, I just this morning started using an AppleScript that Bluefrog provided that does a good job at this1, but I think it would be a very useful for the user to just be able to check a box to accomplish this. This would enable the user to “set it and forget it” at the top level group, without having to repeatedly go back and make sure to exclude new subgroups that are added.
