A snooze button on the calendar task would be nice. Maybe a toggle through the options that are in the task like "later" "tomorrow" "next week" etc

Checkbox "set to complete" tasks in "Overdue" or "Unscheduled" sidebar in the calendar.

as a user, in calendar view, with the task sidebar open, (first image)

I can click on the status of a task and move it to another status, including closed. This requires clicks and mouse controls.

if you added a checkbox somewhere on the line of the task, (like in the top of the task window) (second image)

that would save a LOT of work for people like me who put appointments in their calendar and must mark them all closed to empty the "overdue" part of the task sidebar.

I would like to see the ability to assign custom hotkeys to custom statuses in the calendar view. So I have one status called "holding" - I'd like to be able to assign an H to that status, hover over it, click H mark it. Or, if nothing else, have a (one key) command to bring up statuses and arrow or toggle through them, and mark C for complete or (custom command) D for done statuses.

I have found a way around this issue. Click on your space > Then Right Click to access Space Settings > Click on Task Statuses > Create a "Completed" or "Done" as an active status> Then Amend the Closed status as "Archive". Set the Task to "Archive" Status only when you want to completely close the Task. Hope that helps. Check the images attached.

To add to this - I would like to be able to see completed tasks with a strikethrough line through them on Calendar view. I like being able to see that something I scheduled for a certain date is done.

The other problem is, if you have the option selected to show Closed tasks in Calendar view, there is no way to differentiate if that task is complete if you have the colours set to List colours rather than Status colours (which, personally, I always do, because it helps me chunk tasks in to their different Spaces mentally and visually).

This is one of the (few) things I miss about Asana.

Please add strikethrough on calendar view!

Another way to mark it could be with a keyboard shortcut. For instance, hover over the item in the calendar view, and press C (for Closed)
