Feedback for UI3, flexible side bar for different window

I has 2 screen, one is 14 inch macbook, another is 32 inch monitor. This the premise.
I usually open main work window in monitor, and design library window in macbook, so I can easy find the right design component and directory copy/paste to use it.
but when I adjust side bar width in one windows, it will affect another one.
In 32 inch window, I want right sidebar bar to be wider, but it make sider bar in 14 inch window wider too, and become hard to use since the small stage area for design.
