[Request]: Lock timeline scroll in Federated view when not at top

[atirut-w]

Describe the request

From what I see, Tuba currently does not "lock" the scroll when you scroll down the Federated timeline and instead just stop showing new posts. This gets a little annoying when you're near the top enough that the app doesn't stop the flow of posts. See attached video for example.

Thanks for raising this issue!

There's no such thing as 'locking' the scroll view. When new items get appended, the scroll position stays the same but the content 'moves down'. To overcome that, Tuba has a queue. When you are not near the top, new posts get added to the queue and when u go near the top again, those posts get added to the view. That also matches the mastodon-web behavior somewhat, where if you are at the top, new posts get shown/prepended.

This gets a little annoying when you're near the top enough that the app doesn't stop the flow of posts. See attached video for example.

I understand that the federated timeline gets updated constantly and the 'near the top' behavior is not good enough, maybe limiting it to only prepend the posts when you are at the absolute top then?

Would it be possible to keep the content in place as new contents are added instead?

This could work better than the current implementation, but I'm not a UI nor UX designer by any means.
