So I can do a delete all thumbs older than 3 months, but it wont touch the images in the history list.
I've been messing about with old folders of raw images and discovered that feature too, I like it lot
Eliminated the delay when switching folders while raw photos (thumbnails or cache) are being built.
That is really helpful too. I've messing about with new camera profiles and jumping around to different folders and not waiting for a folder to finish cache building, it's almost instant when I change to another folder to try a new profile.
These are apparently minor changes but do a make a significant difference when using the program, thanks Mike
