A couple of features that come to mind:
- Color-blind accessibility: Change the main color of either team
- No Cosmetic Settings: No mod installation. Granularly choose what type of cosmetic items to disable in-game
- Expanded Advanced Video settings: more console commands should be settings found in UI. I shouldn't have to download comfig to make my game run smoothly.
- Add popular config scripts as bindable actions in settings: C-tap, jump crouch, loadout bind, engineer buildings
