Paging buttons, rather than infinite scrolling

[bclaymiles]

Is your feature request related to a problem? Please describe. Visual fatigue from scrolling through many credentials.

Describe the solution you'd like 'page' buttons - page up, page down, to move one screen at a time.

Additional context I think that the big "+" might be best replaced with paging buttons. Adding a new credential is a much less often used function - aside from the first few times one is using the app - so could easily just be a menu item...
