Something I've always found fascinating is that niche business software often gets marketed heavily on features that are trivial to implement; like how medical appointment software will dedicate an entire marketing section to "sends a [single] reminder e-mail before the appointment, this increases show rate by XX%"
And I feel like it's a really obvious example of the difference between what constitutes "valuable code" to a developer, vs. to an end user
@joepie91 Our dentist ~1 year ago started calling people for their appointment a day ahead, and it's honestly great. It's super useful to both neurodiverse/ADHD people and elderly people. I really like that service :)
