That's interesting. I also have aphantasia and I seem to be the only one around where I work that cares one bit about visual presentation. I suspect it's because people with aphantasia have to rely on waiting for visual recognition to happen so often that we get good at it and rely on it more. I'm also known for figuring out a problem and jumping to the exact file and area in the code that's causing it immediately where others apparently have to read through the code again to find it. I just remember it's maybe 2/3 the way through the file and just past that big switch statement and has a one-liner comment above it and has a distinctive shape.

For me, indenting with tabs and aligning with spaces helps me find the code that I'm looking for as does adequate whitespace and a color syntax highlighting editor. Aligning things with distinct columns where it makes sense helps a lot, too.

Yeah, all of this matches my experience too.
