cooliox besides a ton of bugs and quality of life improvements we're currently working on porting some new maps to iw5. You can apply to become a tester for new features: https://forum.plutonium.pw/topic/3770/alpha-tester-applications-thread.
If you feel you're a "noob developer" you probably won't be able to help with development of the client, if you feel that you do have decent skills in c++, assembly and reverse engineering you can message rektinator on discord and provide him with a portfolio of your past work.
