Yes those would be nice little additions +1.
To explain to STALKER:
1. To allow somoene to "lock" their weapon to a specific mode, thus preventing accidental switching to other modes. EG: An LSW user removing his own ability to accidently switch to "aimed shot" mode.
2. To display the cooldown timers of both first aid and doctor with different colors. This allows those two cooldown timers to stand out, preventing mix up with EG: remaining drug timers.
