Are there any plans to add functionality to generate a side and back view of the character that we are creating? Cause it is very hard to create it manually as the characters may be too complicated to draw.
Welcome to the forum.
No, this will never happen. The main reason is time: It took me 15 years to get to the point the SP-Studio is now. So if I'd decide to draw everything again for side- and backview, this would mean several years of no other updates until I'm done. My visitors would not like this and it would be a very boring job for me. So I think it's better to focus on adding new items instead of drawing the old items for different views.
This would be different if I was working with 3D models, because you can just rotate them. But my drawings are just regular 2D drawings, so every view means extra work.
