There are configuration options for importing pub keys on two different tabs of the GpgOL configuration window.
In the first part "GpgOL" "Import any keys included in mails" and in the second part "GnuPG system (technical)" in the first tab "OpenPGP" "import key from signature" and "put key in signature".
These related options should be in one place together and the difference between them probably better explained.
My opinion here would be add the "import key from signature" and "put key in signature" in the automatition group of the main GpgOL config page and change the wording of "Import any keys included in Mails" to "Import keys from Headers and Attachments".
I would make it explicit because they are GnuPG options and when they are combined with "Import Any key" it is unclear what a toggle / untoggle does with the GnuPG Option.
