Receptive developer
I made a suggestion about making Touch ID optional because the app would loose its stealthiness. The developer implemented this idea in the next update as they have for reasonable requests from other users.
Id like to see a backup/restore link with DropBox like there is for the developers Private Note app.
Id also like to see an option for adding fields in Passwords.
A search function is needed in Notes. There is no option for sorting methods as there is in the Private Notes app.
