What UI would you like to see? A message box indicating the name of the 
trime file, perhaps? Something else? I'm open to suggestion.

The point of doing trimming in the UI is that, with frame thumbnails 
(and soon call thumbnails), you know visually that frame/call to select 
for the trim. You don't need to write down the frame/call number and 
then run a separate app and type in the call set by hand. My 
implementation currently has these two features (thumbnails and trim) as 
separate implementations, but once they are intergrated, ...
