Comment 6 for bug 894143

IMO, considering HIG ( http://elementaryos.org/docs/human-interface-guidelines/user-workflow/always-provide-undo ), you should just hide folder and its contents from view, pretending it's deleted and show something like "Folder x deleted. Undo?". If user clicks undo, set visibility to true again. If not, after some time really delete the folder and its content. (But be sure to remember the hidden state and "real delete" countdown even after restarting Midori, or weird things may happen.)

And please, really allow multiple items selection with ctrl or shift, because I may have 100 bookmarks in folder and want to delete only 50 of them. If you don't know what I'm talking about, launch Files (in double click mode!) or Nautilus, hold ctrl or shift and click on some files.
