Dear development team，
Thank you for creating the best ios sculpt app! It has greatly improved my work efficiency.
As nomad gets better and better, I hope i can just use nomad to finish art work without any other app assistance.
1st Feature Request: Add sliding block in scene panel
Why need this funtion?
Becasue when the scene is including a lot of component, it is very very easy to trigger the wrong function when sliding the panel.
You may consider to add sliding block in scene panel or increase the width of the control panel
At the same time, you could add a grouping function in scene panel .
2nd Feature Request: ：pls upgrade Tube or Lathe tool to creaet non-circular tube, or create one new tool
Why need this funtion?
I usually need to work with non-circular tube,but nomad cannot create this component directly.
So I think maybe you can help me to get it through one of these three ways.
