This clipboard manager is really useful for those moments you want to paste a text you copied but other text was copied after the one you want to paste. Usually you can only paste the last thing you copied but Clipper saves the last 20 things you copied to the clipboard and you can easily access them from the notification bar.

This is the kind of apps you forget you installed until those moments you need it, in those moments you'll be very glad you have it. A clipboard manager is a must have for my PC and I use it almost everyday so I was really happy to find this app when I started working on my tablet.
