The week scheduler let's you see one week at a time with all the tasks you have scheduled for each day. To turn on the strategy, go to ☰ → Features/Strategies → Week Scheduler and when you activate it, you will be asked how you want to access it.

To get to the week scheduler you can always press "W" on your keyboard in the day view or click the "Week Scheduler" tab in the sidebar:
​

Clicking the "eye" button at the top right let's you configure if you want to see 5 or 7 days at a time.

Unchecking the "Minimize tasks" option, shows you the tasks in full-size (just like in the day view) instead of minimized. 

Using these two options you can choose whether events and all-day items will appear above your tasks.

To schedule existing tasks from your Master List into your week, press "X" or click the Master List icon at the top right to open up the sidebar. From there you can drag and drop tasks into your days/sections just like you can in the day view. 

You can add/create tasks directly from the week view. Hover over the bottom of the list to make the plus button appear and click it to add a task.

When using a section strategy, each section has its own plus button.

To edit a task you can either edit the title and use task input shortcuts (#, @, due etc.) or click the Quick Edit icon at the right to open up an edit menu. In the Hover button actions strategy you can untick the "Only show quick edit in week view" option to see all your hover buttons.
