Add filename/titles to warning dialog box when deleting files or folders

[acfogarty]

When I want to delete a file, it's easy to right-click on a nearby folder by mistake. In both cases, the warning dialog box contains the message "You are about to delete 1 item(s). Are you sure?" so I don't realise my mistake until I've deleted the folder and all the files it contains.

It would be helpful it the dialog box message contained the title of the item(s) that are about to be deleted, as in the attached examples.

This would also help somewhat with issues #841 and #617 .

This should be fixed now with the commit 1af7d89. So it will be implemented in the next release.
