While I was doing the problem set I found the "pin" function before each answer result as shown:

I wonder what will happen after I've pinned those. Will I be able to generate a list of those pinned questions afterwards?

I think you definitely can take a break. The goal of blind review is to know your real ability to solving those problems. A break will give your more potential to try your best.
