When adding new pages when the pages tabs extend the full width of their doo-dad or more, and the tabs are scrolled all the way so that the arrow button at the right end is disabled, the new page's tab appears to the right of the old last page's tab and is obscured. The bug: the right arrow button remains disabled. It is necessary to scroll to the left to enable the right button, then scroll to the right to access the new page.

Second this issue - its quite annoying - please fix if you can. Thanks.
