Quick Groups (Instances)

I want this addon to automatically add all collections to the LIbrary scene! I have a bunch of projects where there are already a bunch of collections and their instances, I solved the problem for myself by simply opening outliner>blender file>Collection and pulling all the collections into the Library scene (Line to the scene)

nice work, but an error happens when the name of the object we want to delete contains non-alphabetic or numeric characters

one of the greatest extensions for blender, only one problem need to be solved is when ungroup some of collections it duplicate it over the original one and have to delete every single object, I think it happened only with curves I'm not sure

Is there a way to change the size of the created default gizmo? I am working on small models and that cross is gigantic.
