Prevent preloading certain classes

Hi, are there any hooks and filters available with this plugin, which I can use to fine-tune its behaviour?

I’ve just installed this plugin for the first time – it works amazingly, huge improvement!

However, I noticed that when I open the dropdown menus at the top of my page, all of the other pages listed on the menu are immediately preloaded. This effectively means the user preloads almost the entire website just by opening a couple of menus.

Personally I’d prefer that the menu items are only preloaded on hover, and not simply when the menu is opened.

Is there a filter I can use to control this, eg. by filtering out the menu class, so that it only uses preloading on mouse hover?
