@leofeyer yeppa =) I don't think that this is a problem. A user will be interested in other choices and check the dropdown. With the default installation he'll go like "ah, okay, here I could choose from different uploaders but there's only one installed at the moment so I only have this choice" - there's no problem with that, is there? You can also remove the field if there's only one uploader by an onload_callback but in my opinion that's not compulsory =) Thanks for giving in by the way =)
