I'm uncertain if that can be done Dai-kun.
I suspect that since they are all tied to the same cookie, that it would have to track them all individually, which would make for a significant amount of cookie info. But then I could be completely wrong.
I'm rather ignorant when it comes to how info is saved in the cookies still. That's next on my learning curve.
Personally though, I can't see a reason why I would want to code this to open each individually.
The purpose of the hack is to divide your user's into those that want to see all the extra info, and those that do not. While at the same time making it convienant for them to switch back and forth
I guess it could be written to always be closed regardless, and not save to your cookies. And that user's have to open it to view the info. But I think you would end up irratating the user's that want to see that info all the time.
I'll likely take a look at this down the line and see if there is a way to do that if there is enough interest in that modification, but right now, I won't give an eta on that due to it's priority on my current to-do list
