This is probably the top of my wishlist for the game currently. It's especially bad if you've been watching other people play the game--saw Insym solve the case of the "lipstick killer"and instantly knew where I needed to find a print to solve the case when it happened in my game. Wasn't expecting for there to be "spoilers" in a procedurally generated game!
It definitely feels like the devs have laid the groundwork for more complexity, since there's a lot of things that feel like they should be clues but are underutilized so far--the matchbooks, the vmails, the notes about their performance in their work profiles, etc. Like, it's really cool how the citizens have interests and daily routines in theory, but I pretty much haven't had to engage with this outside of knowing where they live and where they work, because it doesn't seem relevant outside of the occasional case where one of your only clues is that someone is part of the book club. (I've actually had this clue from the beginning on a case and haven't figured out how to learn more about the clubs, but most of the other cases have been much easier so I haven't had to worry about it at all.) It definitely feels like there's plans to expand on this sort of stuff, and I'm trying not to get TOO excited about it because I want to have realistic expectations, but I really hope they have a chance to go crazy with the possibilities there.
I don't want to see the "flavor" for cases entirely go away--stuff like calling cards and weird MOs and the like are pretty rare in real life as far as I know, but they're a huge staple of the genre. It would be great if they stuck around but weren't used for every case, instead being a rare event to make you feel like you're on a truly special case where your perp is particularly devious and elaborate. But even then, hopefully you'd get the higher amount of evidence and red herrings being suggested in the info, so you'd have to dig a little. Like in the case of the "Valentine's" themed killings, you could still have to do stuff like... Go digging in the local enforcer department to find a report that includes a few random bits of info about the "stalker" like the side missions do. You can ask the victim's partner if they know about people the victim was worried about. Maybe there's an even rarer chance that the victim was having an affair and the partner is the actual murderer, etc etc.
