Just pushed out Klicko 1.0b7 (1.0b6 was up only a few minutes).

It now doesn’t block clicks in sheets, has 4 localizations (English, Portuguese, French [by Ronald Leroux], and German [with the help of M. Uli Kusterer]), and the application list can now be of either excluded or included applications.

Please note that if you note unusual behavior, or UI slowdown, with a specific app you can exclude that app (or you can include only some app, alternatively).
