Sort
It’s easy to keep your tasks organized by sorting each list. Just select the three dots in the top right of your list to open the more menu. Then just select Sort and you’ll have the option to organise your list by Importance, Due date, Added to My Day, Completed, Alphabetically or Creation date.
Search
With search you can easily find the task, step, tag or note you’re looking for. Just select the magnifying glass icon to the right of your username to open the search field. Then, type the word or phrase you’re looking for and we’ll check for that search term in all of your tasks, steps, tags and notes. We’ll show you a list of each instance we’re able to find that word or phrase. You can select the desired search result to open that particular task, step or note.
