I think if this gets implemented, it would be great to be able to customise this (e.g. two clicks to mark as favourite, three to skip).
And the usual disclaimer:
AntennaPod is developed by volunteers in our free time. While some developers have started implementing the feature, nobody has brought it to completion, yet. Unfortunately, there does not seem to be a lot of movement, recently. If you can write code or know someone who can, we are always happy about help
