[Excalidraw](https://github.com/excalidraw/excalidraw) is a very useful web app, but the lack of file management can be troublesome and unsettling. We often need to manually save and maintain multiple different Excalidraw files. Therefore, ExcalidrawZ has wrapped it up to automatically save edited files for users and added file grouping functionality. iCloud automatic backup and data synchroniasation between devices has also been added to greatly reduce the insecurity.
