Hi Everyone!
This simple add-on allows you to control Subdivision Surface modifiers on all objects in the scene or only on the selected ones:
- set the number of iterations;
- add or remove modifiers;
- move the modifier to the upper level;
- collapse all modifiers before it;
- increase or decrease the number of iterations;
- hide and show modifiers in the viewport.
For blender 2.90.
