This may have been requested before, but I cannot seem to find it if it is.
In Illustrator, there’s a very handy button which one can press to select all the layer’s contents with one click. Does this exist in Rhino?
If not, do you think that it could be a good little time saver given that it’s likely used very often? Possibly a shift click on the button’s parent layer may select all sublayer objects too?
