I just discovered gomuks and just had to post this [KDE]
Which part of this is gomuks?
Bottom left. Matrix client.
What browser is that on the right?
librewolf with custom css and letterboxing
Thanks, my next question was about the site! I've used custom CSS rules to remove the useless sidebars on stackoverflow, but never thought to change the appearance!
I'll have to look into it and the letterboxing.
