I know mobile clients are capable of this, but honestly - these works well for comments, not so much for everything else.

If any 3rd party software is capable of this, why could not web frontend of Friendica (maybe using some addon)?

Guess that the answer to "is it possible within friendica" is not 😀

@Grischa as soon as we talk about loading other timelines, then you are right. But when you consider interacting with them, you get annoying log-in hassle with each opened timeline you want to interact with 😀

@Hank G ☑️
Not only that it works, but it works pretty well!
