Should go to previous route
The update made it better, but is still not how i would expect it. If i am on page search, communities, notifications or profile (the pages available via the buttons at the bottom of the screen) the app still closes. I would expect it to go to the home tab when i press the back button and only close the app, when being on the home page.
Maybe this is only my opinion and the behavior is good for everybody else, but i thought, i share my expectation for this :) My Expectation is also based on the fact, that when reopening Openbook the home page is displayed and not the page, that was active when leaving the app with the back button.
@Andi Perlitz: Yep, will make sure it works as native to android.
@Andi Perlitz: Going back to the home page feels more natural to me too.
