The developer has worked hard and fast over the last couple of days to sort out the bugs in this little app and now it plays very nicely. It's good looking, simple to use and efficient. I have tried a great many of these types of enhancements and I use Shadow Clipboard and iClip and have done for some time. However, I see no reason why Clipboard Evolved shouldn't get serious consideration if you aren't looking for things like multiple clipboards etc. Give it a try. If only to see the cute window effects!
