In Ambient, the way of handling multi-selection different (inherited from Directory Opus, FileMaster and other traditional file managers). So, drag and drop cannot be handled like on other file managers with no direct multi-selection.

On other file managers you need to use a secondary qualifier to do multi-selection, which is also a pain.

I'm not sure there is a way to have both usages optimal (direct multi-selection and drag and drop). In Windows version of Directory Opus, you have to choose between "power mode" (direct multi-selection) or "basic mode" (direct drag and drop).
