I have a list of items in a tree in a column on the left of the page. Each item can be added to one or more views by dragging the item onto a view on the right of the page.
This is proving to be time-consuming and non-intuitive for the user. If there were only one view on the right, we could add or remove items using check-boxes. However, there are potentially many views.
Is there a better solution to this problem?
