UI change request

[galerious]

We'd like to be able to swipe right from anywhere on the screen to go to the previous page from the gallery page or search results page, rather than swiping from the left end of the screen to the right.
On the first screen when you open the app, or the favorites screen, you can swipe freely to get to other pages.
We'd like to see that work on the gallery page and the search results page.
