It’s something I’m missing in all the apps I’ve tried so far, but it would be cool to be able to quickly see the new coments since last visit on a post.
I guess using different background would be enough and maybe provide a way to navigate between them.
For the reddit website I had an user script with a slider that was using the time of the last page visit… And that you could adjust.
So maybe something similar? Like the app remembers last time a post has been visited (with some garbage collection after a while), then the user can use a slider to highlight the new comments since X time.
Also if the API provides you the number, can’t you just iterate back from the latest in time and count until you reach 0?
That would be a cool way to do it actually.
