Can we have a firewall feature

Hi there,

just trying out Blokada 5.15 on an Android 9 device, coming from “No Root Firewall”, which I have been using a long time now. This app generally works well but it has its quirks and hasn’t been updated for many years, so it seems to be abandoned by the author (it’s not open source anyway).

One feature of above mentioned firewall app was to block outgoing communication for certain apps completely. There are apps who work locally and thus have no need to communicate with internet servers - each communication attempt of these apps can be considered as tracking or ad fetching. Is Blokada able to “blackist” an app this way? It’s possible to whitelist an app, so Blokada leaves all communication pass, but is there a “no-pass” list as well? (I haven’t found this possibility in the settings, but I may have missed/misunderstood something…)

Thank you!
