Turn off screen rotation
In the settings, be able to choose to always keep the app in portrait or landscape orientation, regardless of if screen rotation is turned on in the phone settings
This will be added to the next version of the app. A 1st beta should be available in the next couple of days

I also want to prevent screen rotation, not just when watching videos. This should be a feature.
Yep. I am always telling Android to enable screen rotation lock when I launch PodcastAddict and then disabling the lock when I am done with PodcastAddict for a while and then reenabling when I next listen to a podcast. If only PodcastAddict had an option to always remain in portrait mode.
You can already lock the video player screen if you want to
