Damn-it, use background threads for your disk/thumbnail activity!

Whenever I browse to a folder of sub-folders, or a folder containing many images, you run some sort of CPU-intensive activity on the FOREGROUND THREAD, thereby making Bride useless, for many minutes in some cases. I can only imagine you're updating some cache or thumbnails, but PLEASE, run this operation on a BACKGROUND THREAD so that I can make some use of Bridge, otherwise it's just a brick paperweight. THANK YOU.
