As many people use more than a single monitor, would it be possible to make the sidebar (and indeed any
tool bar) detachable and expandable. A second screen could then be used to accommodate tools/assets etc. When using many instances of the built-in models (trees, grass and the like), scrolling to find one in
particulat to omit or edit can be a pain. This workflow I use all the time in Sketchup.
If this is already a feature, I apologise, and would be grateful to know how to do it.
