Ok, Likes display behavior has been drastically improved. Comment footer actions has been redone. Comment likes display has been redone. Comments can now detect if it's a reaction. A reaction is an emoji, sticker, or gif. When it detects it's a reaction it suppresses the background display and enlarges the text to 300%. This allows large emoji reactions. Check it out below!
The like buttons and links will also respond to the type of like you've performed. They also will change their color based off that. This means Like Types configuration has gotten a lot more robust to allow for configuring a types primary color which is used to adjust the text color.
You'll also notice the timestamp behavior for comments now uses a shorter display.
Also forgot to mention almost all the margin spacing between elements has been and is being removed. They are all being converted to flex or grid CSS styles. This allows the usage of the "gap" CSS rule to easily customize the spacing, direction, and order of elements. One example is comments direction in activity is reversed. The default order for comments to top down, but with 1 simple CSS rule it's reversed to fit activity discussion flow.
