Back button in in-app browser

Can we get an option to change the behaviour of the Android Back button when using the in-app browser?

My preference would be that it would act like a browser back button and take me back a page if I've browsed beyond the initial page I went into the browser for. The in-app back button at the top left would still always take me back to the post or post list like it currently does. Additionally, I'd prefer that the Android never brought me out of the browser, even if I was on the initial page, but some people might not like that.

Or... Having a dedicated browser toolbar with back, forward, refresh and the url would be ínteresting.

Thanks for the awesome app!
