Info:
ZSceneManager’s main features are :

You can hierarchically arrange your SubTools into folders in a separate window.
Based on multi-SubTools selection, you will be able to easily execute actions on multiple SubTools in a single click. (renaming, deleting, change visibility…)
Sculpt, Paint and Pose multiple SubTools simultaneously by using the ‘Merge for Sculpt/Paint‘ and ‘TPoseMesh‘ commands…
Visibility configs allows to quickly switch between different configurations of your Tools.
More generally, ZSceneManager greatly improves and speeds up your workflow when you work on a lot of SubTools.
