Currently if you create a new thread and look at it through your subscriptions tab, the folder will be highlighted yellow even if you (OP) is the only current post.
Once you click said thread (that still only contains the OP) any subsequent time you hit the subs tab it will show the green arrow next to the folder, making it appear that someone has responded but only because OP opened the thread.
Is there an easy way for that green arrow to only appear AFTER someone else has posted a response? Yes, landscape view will tell you who last responded to the post, but I’m lazy and turning phone 90 degrees is far too much work.
Just a small QOL change that I believe would be useful.
ETA: I opened my subs tab and it already had a green arrow as if there was a response to this post, which it did not.
