The possibility to adjust the length, thicness and colur of the normal indicator within the viewport display. A further enhancement could be different coloured normals based on hard, soft-edges or angle.
Justification
At the current normal indicator settings, it can be difficult extinguishing one normal from another, making normal analysis time-consuming and prone to failure.
Implementation
All options/preferences (length, thickness and colour) for the normal indications could be located within the Viewport Settings → Scene Settings menu. Upon activating the normal display feature through the hotkey or the viewport switch, the Normal preferences could be made available for modification.
Any wishes or ideas?
