We tried stretching content to 100% of 27" viewport but it looked too cluttered. Imagine if you were reading a book where page width was half meter long. I hope you understand what I mean.
We could left align it tho. Didn't really try yet. Thanks for the suggestion!
Not really a criticism but more of a question as I'm not a designer by any means:
Why do you only use a sliver of horizontal screen space in the middle?
I only mention this because it looks slightly unusual on my 27"
