I’m using the TT-RSS Android app version
1.281 (515) on my mobile phone
Android 188.8.131.52, 5,9" display, and tablet
Android 10, 10,5" display.
I think it would be a good option to be able to hide the article list in landscape layout on the tablet. At least on the mobile phone does not show the article list in the landscape layout.
Please refer to the following screenshot. I could only attach a single image.
