Hey @CCP_Avalon ~
I do see a lot of people talking about the small portraits, and I’m sure many would like to see an option to make them bigger - there’s a thread where some of us have been looking at how to fix that, and if you’d wanna take a peek and see how you like it, maybe that could lead to a portrait size option ? 
[UserScript] Avatar Size & Sub-Category Adjustment
There’s a user script there that does exactly that if you wanna look, it makes the portraits bigger but circular still so it fits the look of the forums (Erika made the larger portraits script & I just re-did the circular frame below). Though I’ve gotta say, small portraits is absolutely the way to go on mobile - the whole layout works perfectly ok my phone~
