Hello, @noxfox if it's problem, You can just write this code to console (press ctrl+shift+i, click on console):
document.querySelector("#comment-section").style.width = "800px";
while You are in comment section.
btw. You can rewrite that number to any anything, if You choose 1920, it will expand to fullscreen.
it will expand place for comment, it will little broke website, but don't worry, after refreshing (ctrl+F5), it will get to normal.
I'm working on few browser extensions, and I think, I can look on it, so it's easier for users.
I know it's not good solution, but I hope it will be enoguht to time, when Tapas will change it, or to time, when I create browser extension for better UI/UX for Tapas.
