I’ve been already missing this feature sometimes, even more now with the addition of ‘Brainstorm with Kjun’.
Buttons on the right that let me jump to the ‘Top’ and the ‘Bottom’ of the thread.
In long threads (like Kjun’s, for example) I sometimes want to take a look at the first post again - and when I scrolled all the way up, I also have to scroll all the way down again to reply.
So these buttons would be a great help for me
