I have a couple of suggestions I have to present that could potentially improve QoL of the game.

1. Ability to add personal notes to enemies and friends individually from your lists.
2. Push notifications option for new DMs
3. Ability to mention someone with their name or game ID in global or cartel chats
4. Ability to add custom shortcuts to left panel (Wheel spin, Market, etc.)
5. Cartel Roles to appear in profiles
6. Additional casino games.

tldr: Diablo do this!!! its good! <3

1. You can do it here Friends & Enemies | Cartel Empire
2. Why not? as long as its togglable option and you can select people who you get notified from.
3. This i like its bothersome especially with someone that got a long as names.
4. GET MEGASCRIPT!! Joke :D
5. I like this <3
6. More money sink! I like it!
