Sure.
Well, i got a folder here which is called "pending".
Inside that i got a few other folders: "idea", "in preparation", "to wait for", "currently active"
And on the first subfolder of each of them i got some Hazel rules defined which let me know if there are any projects i am not interested anymore.
Let's say i haven't modified something inside "idea" for 4 weeks it's VERY possible that i am not interested in this project anymore and it was just one of those "ideas

".
On the other hand there are maybe some files i haven't worked on for 4 weeks inside "to wait for". And therefore i should email the guy whose answer i am waiting for if he is still interested in his project.
The same goes rules i've set up for the other folders to see if am a lazy dumbass or currently working on something.
To make it short. I do want to to have a Hazel look inside each of that folders (subfolder of pending) but not any further (because there are files/folders inside which do actually belong to a project).
By now i have to drop each folder to hazel and duplicate the same rules to each of them...
Is that clear enough?
