It would be great if imported models would automatically create tags, For example if I import people, that it creates tag in SketchUp labelled "PEOPLE" for example. few general category tags would be already enough.
Not a big thing but I often forget to tag models when creatively choosing and importing. and if there collects a lot of models placed around, it can take some time to tag all of them separately. would be neat addition :)
This feature is planned for some of the future V-Ray for Sketchup updates, and will be announced, when ready.
