When the tree is larger than the current view, then it can happen that the user inadvertently selects multiple items: if there already was a selection outside of the current view, and the user selects another item in the current view.

(This is possible because multiple selection in Magnolia is with checkboxes, while e.g. in Windows Explorer it is done with Ctrl+Click)

The number of currently selected items should always be visible, e.g. at the bottom, or even more information on the multiple selection should be shown (selected names).

Currently the bottom only shows information about a single selection. On multiple selection, it shows only the name of the first selected item.

When deletion is chosen on a multiple selection, the confirmation dialog message hints at multiple objects being deleted only by an additional plural "s". It should state the number of items going to be deleted, and maybe also paths.
