Empty images
Possibility to create an empty image (image size is selectable) which is not write protected, i.e. you can write to the mounted volume.
This is impossible. You can not edit iso images in the normal way you would a HDD.
I have searched and searched, never could find a solution. As recreating images was a pain, if you only wanted to add 1 file.
Drag and drop image creation
If you drop a drawer or a disk to the AmiDVD window, the following fields will be filled for you: "Create image/Source" and "Create image/Volumename".
Now, that would be a nice feature.
