feat(editor): the node bank in two panes, as the assets of unity: its groups on the left with the scenery templates, the entries of the chosen one on the right, as cards or a list, a search going through all of them; the models dragged from the node bank onto a model set, the templates of a set or the list of the brush or the area fill; the templates of the model sets shown with their previews; the model sets docked by the node bank by default; Polish translation
