Hi, I just submitted feedback to Apple and since I am confident that they wait until there have been many people complaining about the same issue before they actually try to adress it, I would invite anyone on this board who feels the same about this to submit his/her own feedback to Apple... btw: http://www.apple.com/macosx/feedback/ I think that's the only way to get somewhere. I posted what I wrote so you see what I am specifically complaining about. "Hi, this is really one of my MAJOR gripes with Mac OS X and I've heard from lots of other people that I am absolutely not alone. Windows is actually way ahead of Mac OS X in this regard. It has to be possible for previews of images to be quickly created and shown. While it takes merely seconds on Windows it takes MUCH longer on Mac OS X . Additionally, Mac OS X doesn't even bother to create previews of image files in the current folder that are not shown, so it only starts 'building' them when you scroll to the files at which point you'll have to wait AGAIN. What I have noticed is that the preview speed is acceptably slow when you still have RAM shown as 'free' in the 'Activity Monitor'. Once there's none left (after you have looked at lots of previews), it can take up to a MINUTE before Mac OS X continues showing previews of the next pictures. This is true, even when you have closed the current folder and you have opened an entirely different one, trying to get previews of other pictures. I REALLY hope this issue can be adressed in Tiger, I feel it should be a top priority, since it is a requirement for a modern multimedia OS to quickly browse through image folders and show a lot of previews. Thank you very much for listening to my criticism / suggestions. Yours sincerely," That's it. Good idea ? Bad idea ? What do you think?
