I have a native resolution of 1920x1080 (I even use a very wide bookmark sidebar on the left), and as I look at all the pages of this thread I don't see too many lines of text that actually hits the right side of the browser (ironically majority of the posts that do are by The_Ed, and he doesn't even care
) ). Even with my browser not on fullscreen, majority of the lines of text don't hit the right side of chat window. I honestly don't see how increasing the possible size of the avatars and the left margin by a few pixels could really hurt anyone.
This is just my opinion, of course. I do not speak on behalf of those with lower monitor resolutions.
I also like seeing lots of nicely packed lines of text
) It just looks so neat.
