Change the function of the R key to "switch" to change the construction mode of the conveyor.
Why:
It is quite often necessary to change direction when building conveyor lines. "Mindustri" has made this very convenient: the conveyor automatically rotates in the direction of the mouse. In Factorio, you have to press the R key to do this, which is quite inconvenient to do while moving.
Benefits:
Changing the construction mode of conveyors would be a very convenient feature. In the "rotate" mode will allow you to easily and quickly build winding conveyors directly in motion. Also switching to "standard" mode will allow you to quickly build conveyors on different lines in the same direction. This is especially important at the beginning of the game, when you have to build everything manually.
