I would rather match Discord's timestamp sorting. Duplicates grouped with the original and new reacts added to the end.
I think Discord keeps reacts in timestamp order. Duplicates are grouped with the original, and new ones are added at the end.
Agree with part 1. When I'm trying to decide which of two different reacts to add, it's helpful to have both in view at the same time.
I would expect to see reacts displayed in the same place as the react button (immediately after the karma buttons/display). If reacts are left-aligned just below the username/karma line or at the bottom, then the react button should be there as well.
We, the site moderators, don't take for granted that what makes our community special won't stay that way without intentional effort.
The double negative here distorts the meaning of this sentence.
Also, when scrolled fully to either end, there remains a large space of the background color that makes it look like the bar is not fully at the end.
