It's planned, but there is still some work to do, and its not my top priority. One reason is it won't help in cases like yours: If an app has got root, it can probably just capture keypresses or trick you into signing their transaction. Encryption just puts the bar a little bit higher for a successful attack, but its far from a silver bullet.
Yep, I understood it

Thank you for your answer and the application (amazing app).
Just one more thing, the transaction on the "home" show something like :
1 BTC from ADDRESS
Would be great if ADDRESS was replaced by the label of our address.
