I've got 4.5b36 on iOS 7.0.4 (iPad Air).
1) When I swipe from the side of the 1Browser screen, (left or right side) 1Browser doesn't go back or forward, like what happens with Safari.
2) When in 1Browser, I no longer have an option to search all my items for a specific string and then have a tab open the associated website if I select it. I only have the 'login using' lock icon that matches websites only if I already have the tab already at the website. That seems to include all my identities and credit cards, but I cannot expand my search to any websites beyond the one that's open in the tab.
