Let's layout the initial template structure for a SaaS app that provides a home view with a left-hand sidebar with "focus modes" for daily and weekly planning. Then a kanban board for easy drag and drop of items across a horizontal scrolling timeline (current date and next 2 days in view by default). On the right-hand side is a list of integrated apps. Clicking any of these will open a vertical drawer with a list of items that can then be dragged onto the kanban board.
