Regardless of whether the design task is in progress or completed, you can click "Save" at any time. The design task will be saved in a proprietary format (.drawtify) to the location you specify, and then you can edit it again at any time.
Drawtify Designer Online will save online to your dedicated storage space, which can be viewed in the dashboard.
Of course, you can also click "Preview" to view your design tasks in real time to understand the expected effect. And supports black and white environments.
