I'm sure whether this is a future consideration or not, but it's still a good idea i believe.
You could import files to fusion app when you're offline and later when you have internet connection it syncs with your account as it is currently.
Right now every time i want to import and modify something i downloaded from here or grabcad i must wait for the upload to complete. This is really a problem with large files and slow connection because it takes so long to upload.
Thanks!
