1). A “back” button. Yes the new forum is easier to navigate, but there are cases where a simple back button would be a drastic improvement.
2). Not sure if I’ll use the right terms here. But this new forum needs some memory or caching. If you leave the app for any reason you get taken to the topics screen when you rejoin.
Example: I’m reading a large thread and am about 1/2 through and get a text. I reply to the text. When I go back to the forum app it takes me to the main screen, so then I have to select the proper forum, find the topic, then find where I was in the topic though is seems to remember where in the thread I was most of the time. But still. Why does it take me to the start screen everytime I go back to the app?
3). It’s been talked to death. Ignore. Bring it back. It’s needed no matter what the pie in the sky lala land developer thinks.
