I think it would be great if the floating windows for materials, components, styles, etc. were unable to cover the bottom right input window.
Perhaps this is an issue only on laptops with smaller screens, but frequently I will start to draw a line or move an object and realize that I cannot see the box because a window is on top of it. I then have to escape out of my action and then move or close the window and then do it again.
Maybe if the move or line tool was engaged, then this box would come to the top of the screen. Or perhaps it could float close to the cursor like in AutoCAD.
