We're testing a couple of new features recently introduced to Localized Calls Blocker.
In some houres a new stable version will be available on the Android Market with those changes:
1. Toggle button to show/hide notification icon (to improve privacy and make the app invisible)
2. A new button to manually force a refresh of blocks list (actually it solicits a refresh, but since it depends from the Location Listener, it's not sure it will really refresh)
Stay tuned and check on the market!
