Is it possible to move to archive a whole project? I'd like to do this when I finish all the project tasks.
unfortunately, it's not possible to archive a project right now, but thank you for your feedback, we appreciate it and will consider adding such feature in future development.

For now, as a workaround, you could create an archive manually. To do so, please create a new project and put an asterisk * in front of its name and then move the project you would like to archive below it, make them sub-projects and you'll be able to collapse them.
Here's a short video showing how it works:
Good idea, thanks. Waiting for the decision of the request!
Thanks for the Work Around tip. Its great that I can keep the old completed projects for reference.
