I just noticed something as I was looking at cards in a gallery.
I did a search in the store.  Then selected a card from the search results to look at more closely...  After looking, wanted to return to the search page in the store and I could not return to the search page or the store with the back arrow.  Had to click on the store link and start all over again.  Is this normal?  If so, this is not too user friendly for stores/galleries.  Would be best to be able to return to the original search page.
 
Thanks,
Kati
