After answering a few questions on Code Review and Stack Overflow, I noticed that the editor allows you to resize vertically, but not horizontally. The width seems to allow 80 characters.
My questions is:
Why not allow high-resolution monitors users to use some extra horizontal space (i.e. on the left) when editing answers? This meaning that the text-area allow resizing to the left, if window width allows it.
My arguments to allow that:
Some programmers think that 80 chars/line is too small and might compromise readability as pointed out here.
Since Code Review is about asking for help about functioning code, this usually means lots of code, typically much more than plain text. I would optimize the editor for code editing, rather than plain text.
Many of us who post a question here are not that experienced to pay attention (or "OCD" enough, as I use to say) to line width, cyclomatic complexity (typically meaning large indentation levels) etc. and the code is very hard to read.
Here's a sample image of code showing improperly:
