"As far as basic concepts go, Clearboard is very basic, but the simplicity is useful in that it does what it needs to in a predictable and logical way. The animations are quite nice too, however I'm not exactly sure I really need to even wait 3 seconds to clear the clipboard. No fault to the app though, just a preference of mine. I'm extremely pleased with Clearboard, enough so that I'm considering buy the addons. I suggest that everyone install Clearboard and run it daily."
We will take your comments into consideration for the future enhancement.
Currently, there is a "Sudden Death" style included in the In-App Purchase pack. It will clear the clipboard without any countdown. But obviously in this style you will not see the animation that we love so much.
