Now i want to find the best library for cross-platform window & input managment. GLFW is a good choice: nice API, clean and simple code. But after input system investigations I found, that GLFW uses WM\_CHAR/WM\_KEY\*/WM\_SYSKEY\* and other messages. It is slow. For low latency input only raw input is correct choice on Windows. Reasons:  
-low latency - WM\_INPUT is underlying message for others  
-simple - one message for keyboard and mouse (but can be a problem for non ASCII input)  
-valid way for high DPI mouse handling  
-my favorite FPS pro-game Quakelive used it 🙂  
-ability to disable legacy messages for preventing message queue pollution

So my question is:  
Do you planning to add support for raw input? If yes - when? If no - why?

P.S. Library is really, really very good 🙂
