Just out of curiosity, are you requesting this feature so that you can make your whole website HTTPS? You can actually do that without the plugin by changing your Site URL in the General settings in the WordPress admin panel to be 'https://' rather than 'http://'.
I'm not sure if there's any need to default all the pages to HTTPS. I can't imagine a situation where someone may want all of their pages HTTPS, except a few. Usually, it's the other way around.
However, convince me otherwise and I'll consider adding it. :)
Also, the attachment bug will be fixed in the next version. I hope to have it out very soon, but I have a few more bugs to fix before I release it.
Thanks for downloading, and thanks for the feedback. Greatly appreciated. :)
