First of all, I love Norway having lived in Bergen many years ago. But, I have some issues with the Lion Tweaks. I made a recent move to Lion and so far think it sucks and my first impression is that it will eat up more time and cause more frustration than the benefits I will hope to see happen. The FINDER is for me such a critical part of OS X. To make the icons grayed out is just plain STUPID. The Lion Tweaks does not solve this problem completely. After every restart one has to repeat the process with Lion Tweaks; for me this is a partial resolution. On a positive note, my MacBook Pro (MBP) was bought back in the "dark ages" of 2008 and so Lion does not recognize Airdrop. Lion Tweaks seems to have fixed this but will not know for sure until I use it.
A second work-around for the colorful icons is to RELAUNCH the Finder by using Command-Option-ESC (force quit shortcut keys) and select FINDER and select Relaunch. That is no less work than opening up Lion Tweaks and checking the colorful icons box. Moreover, if one uses the Force Cut as above, and if you are using Total Finder (a great app BTW) then Total Finder has to be restarted too.
So far I am very grumpy about Lion. I think Apple Developers have their cerebral cortex inserted in the lower portion of their GI tract. I hope I apologize for this slam of a company I have been so wildly enthusiastic about.
