local storage doesn't work.
here's what I made
there if you click the items on the list, they are cloned and showed up at the bookmark page
the problems are
1. local storage doesn't work
If I refresh the page, the bookmarked pages are gone.
2. After I bookmark one item in the list, if I click that one again, it show up again at the bookmark page.
I don't want to store same pages.
3. I want to limit list numbers 'only' in the bookmark page.
