drop installer?
 

i'm sure you know oggdrop, which is an application to which you can drop wav files in order to encode them to ogg. i was wondering if something like that interface was possible with nsis, maybe with ioex? drop a file on a bitmap, detect it with getparameters and do something with it.

You'd need to modify the InstallOptions plugin or create your own to allow controls to accept dropping.
