I've actually 2 questions.
The first one, simpler: is it still possible to create filter manually with a Boolean string or do we have to use the filter tool (the form it comes out when you create or modify a filter)?
Second one: I've a filter which puts all messages coming from
email@example.com in a "work" folder. Let's call it "WORKFILTER". Great, it works!
I want to put some of them in a subfolder "work/subfolder1" but not to give them the "work" label (only "work/subfolder" label).
Is it possible to do that only with a second filter (let's call that "SUBFOLDERFILTER") in which I archive the message coming from
firstname.lastname@example.org with the label "work/subfolder1" but NOT with "work" label?
from:(email@example.com) label:"work/subfolder1" AND NOT(label:"work")
Or do I have to modify the "WORKFILTER" specifying to label with "work" all the messages coming from "firstname.lastname@example.org" but not the ones coming from "email@example.com"?
