Where do I look to see the number of tasks I have in Todoist?
Unfortunately, that's not available. You can type "view all" to the search bar to see all your tasks, but you can't see the total number of your tasks.
You could add up the task counts from the projects on the left and if you have sub-projects, collapsing them will add the task counts of the entire structure automatically.
When will this feature be available?
There is currently no projected release date, but it is among a group of features being worked on by our development team.
