Quality of Life updates may not be what most people are waiting for at the moment, but it's small stuff that probably wouldn't take too long to implement, and it would in my mind add a bit to the player experience.

 

Search bar in events

• It would be nice to be able to search for specific events, like when you last OD'ed, check who have mugged you over time etc.

See reputation contributed to your cartel

• I was constantly wondering how much rep I contributed to our cartel while rep farming and how much others contributed, so it would be nice to have that listed in the cartel on the member list or something.
• other suggestion thread including an example of how this could look

More stats in personal stats

• I think it the personal stats page should have more stats, like how many drugs used, how many OD's etc. some of this you can already see in your achievements and the current personal stats, but I would love to have more stats to look at.
• It would also be cool if you could compare stats that are already in the public API with other players.

Stats for all casino games

• There's already stats for blackjack, but I think it would be nice to have for the rest as well.

Job stats

• I would like to be able to see how much stuff I have gained through a particular job, how many of the different jobs I've done etc.
• I imagine this would show total money, rep and items gained for the individual crimes.

Likes/dislikes

• Fill in the hands when pressed, so you can see if you've liked/disliked something earlier
• Already made a suggestion earlier, but wanted it in this list as well

Fix chats

• Sometimes they're lit sometimes not, and they don't necessarily stay lit when there's new messages you haven't seen yet

Forum feed

• Would be nice to have a feed where you can see if someone have responded on or liked one of your threads or if you've been quoted

 

This was what I could think of at the moment of writing, feel free to add to this in the replies and I might edit/add stuff to the list if I agree.
