I love safe-in-cloud password apps for android but........
I would like the developer to add in-built keyboard (similar to a.i type keyboard plus, with number pad (3/3), also top row above alphabets) to be included.
Keyboard should display 1 button for username, 1 for password and one common button for filling other credentials. (Similar to KeePass2Android does)

So that one feel secure and fast while navigating between sites

It will bring max number of customers to you.
