tile open finder window
This isn't really a question because I have spent the last 30 minutes skimming through a few years worth of complaints and questions about tiling all open finder windows. Just airing a little frustration about the lack of this ability. It used to be possible on OS9 and it really makes no sense to me that Apple has removed it. The other options ( mission control or expose ) just don't help if you want to work with multiple Finder windows at once and you don't want to fiddle with manually placing and sizing them. At this point, I imagine Apple has absolutely no plans on ever fixing the shortcoming but I would still suggest submitting feedback if you are interested in having this funtionality back.. pointless as it may be. http://www.apple.com/feedback/macosx.html
In the event others don't want to be forced to work the way Apple sees fit, there are some options available. This one looks good.
