Comment 12 for bug 823199

Ok, first this is a bug tracker, not an user forum, we don't focus on "who is right or wrong" but on "what are the issues and how to get them fixed" so no need to be confrontational

The fact that kate is capable to open any file is interesting but what is the interest to drag a dvd .iso to kate? The intend there is to let users know what are the softwares likely to be able to be "useful" for the file being dragged. If somebody is dnding a jpg the goal is likely to open it in an image viewer, not in a text editor or IDE.

That said the complain there is valid, unity should use the information it has to hint on what software would be useful and not block the user of other ones, way to solve that would be to let .desktop claim that softwares can handle files they don't claim to support with their mimetypes, one other way would be to let dnd on a "non-suggested" icon

Note that "special case" doesn't mean "not useful", the software you list are very useful ones but only a few software, most applications handle some formats only
