I did not ask the question in fdroid.
I remembered this feature in a Lemmy convo. I searched for the link and info to comment there. After that, thought that it would be good to share to fdroid sub, as it would apply there.
After that, thought whether there would other features like this in popular apps or extensions. So asked here.
Do you categorise this as spam because you saw it in 2 communities? Wouldn't spam need more copies? Or is it something unwanted?
