great app... "Version 3.8.3 2099-12-31 UI changes & more New option: Flight mode" I'm wondering where to get this update. (I have the "DefimDonator.license" file in storage) Also, like someone else already mentioned it doesn't block any browsers. No problem for me. But how can I be sure it won't fail to block other apps

Doesnt work for browsers?. I blocked all connection for the browsers but i could still browse normally. The logs showed it denied chrome and opera connections. Note 3 jb4.3. Xposed v2.6.1. Stock ROM/Kernel

It works and does what it say it does. However, major functions are lacking. No import/export, no filters of any kind, no batch rule application and its not clear how the templates will work. Can there be multiple templates, is it one that applies to everything? I can't justify donating as the app stands right now.
