Hide on Custom Post-Types

Am loving the +1 plugin - super simple to configure.

Just one problem I've found - in the config I can turn off display on Posts/Pages/Attachments. But not my custom content types.

Using Pagelines' Platform Pro there are a lot of custom content types (homepage slider items are custom content types for example). I'd like to exclude these content types from the +1 plugin's scope. Is this functionality in the roadmap, or should I go ahead and hack?
