This was my thought as well.  I didn't know something like ignore-list already 
existed (how does it work?), but it seems like it should be there.  When KPA 
looks for new files and finds files that are not types it can handle, it 
seems to me that it should add them to a list of files to ignore and 
thereafter should never examine them again.

That, however, raises the possibility of a situation where a formerly-ignored 
file is replaced with a new file that is a valid image or video that KPA can 
handle.  So either the ignore list also has to store ctimes and the new image 
scanner has to check them when deciding to ignore the file, or there needs to 
be an option in the GUI that allows the ignore list to be cleared.

I think with the addition of something like this, the MIME type scanning 
wouldn't be a performance problem, since a given file would only be checked 
once.  That said, I don't think the complexity of automatically building and 
maintaining the ignore list is justified by the value of the feature.  
Whether or not you like filename extensions, they're a fact of life 
everywhere, not just with KPA.
