Update: today I counterd 190 applications in extras-testing repository.

As mentioned above, surely many of you are already using applications that are still in extras-esting and must be rated. In this case, you do not even make the effort to download applications you do not need, you can give a hand to those already you are using. It can be very helpful to use a application that tells you what applications you have and which are extras-testing.
This application is called: "KISSTESTER".
