#4556

Is it ready for merging, or does it need work?

i am not good at cpp,so i am not sure substr is a good idea,but i think m_szName need to be fixed when tooglespecialworkspace

[PostCyberPunk]

emm...how about that or maybe add a prefixid:,so you can pass m_iID directly to to togglespecialworkspace function?

Easier to use the function directly
