Show usage of templates, scripts and voxelmeshes in current world in editor

It would be great, if we can see from the editor’s asset window, whether a template, script or voxelmesh is in use in the current static world entity tree or not. I know that it is not a final answer whether an asset is in use or not, as they could be dynamically spawned or used in another world, but nevertheless it would really help a lot when cleaning up projects. Currently the only way to find it out is deleting, looking for errors and undoing, which is a time and resource intensive process. Especially when importing packages there is usually a lot of unnecessary assets in a project that consume at least loading time.
