Need improvements – Inbox by Gmail Review

1) top blue border is too bright 2) very less contrast between read and unread messages. Blue left corner new mark for unread messages will be helpful 3) left menu categories should be customizable( show/hide) 4) no need of pinned button on top, that button can be included in left menu, instead above space can be utilized for search bar ( present search button is too small to touch precisely) 5) sweep button is creating unnecessary attention.... Don't think it's useful. 6) compose button is too big, occupying screen space unnecessary
