If you create a new app using eg. tabs template, it will have a back button in index.html using ion-nav-back-button:
The nav bar that will be updated as we navigate between views.
The views will be rendered in the <ion-nav-view> directive below
Templates are in the /templates folder (but you could also
have templates inline in this html file if you'd like).
In the docs of ion-nav-back-button it shows how to provide a custom content of the back button.
Thus you could use a explicit image and back button title.
<i class="icon ion-..."> Back
Just like we can do <ion-view-title> to specify the title including any HTML, perhaps there is a similar way to specify the back button content for each view so that it is possible to write out the destination of the back button.
