What are the sections in the sidebar?

The top lists your task views and lists (Inbox, All, Planned, Completed, your own Supernote lists, and a Pushed tasks folder once push is set up). Below that are two collapsible sections: Settings (Scheduling, Task apps, FAQs, plus your device connection) and Quick actions (Sync now, Push now). Click a section heading to collapse or expand it; your choice is remembered.
