Your inbox is now your to-do list! At the top of the inbox, you will find the to-do section, which contains unread message threads, notes, and triggered reminders.
Reading a message automatically marks it as done. Items can manually be marked as Done from within the inbox by hovering over a note or reminder and clicking the “Done” button.
A to-do can manually be added by typing it in the "Add a to-do" field.
Below the to-do items is the Done section, which contains your read messages. To revisit an important thread later, set a Reminder that will make that thread appear in your to-do section at a specific date and time, or just mark it as to-do, which will immediately move it to the to-do section.
Click "Hide Done" for a cleaner inbox experience. To archive Done messages in your inbox, this option can now be found under "..." next to the "Hide Done" button.
This feature can be disabled under Twobird Settings > Toggle off "Treat unread messages as to-dos"
