Does the option exist to disable the functionality whereby double clicking on a folder in the bookmarks bar ('Favourites') opens every bookmark within that folder?

Although I certainly see its usefulness, I am finding myself opening hundreds of pages at a time by accident every day. As a result, I either have to kill my WiFi (to preserve bandwidth) and/or force quit OmniWeb.

I realise this is 'user error.' That said, on a laptop it is surprisingly easy to trigger this functionality by accident. Additionally, as the option to Command + Click exists to perform the same task no functionality would be lost entirely. It is additionally easy to trigger this functionality by accident when opening a folder does not respond immediately, causing me to click again without thinking.

Thanks for listening. I have searched and found no obvious solution, but hope to be proven wrong.
