A checkbox that allows you to select "all" titles on any of your lists or search results from your lists(wish list, on hold list, etc., etc.) and an option that allows you to mass delete or mass move all of these selections.

I really hope such a function could be added. I don't know if such an option has been suggested, though.

YYYYYYEEEEEESSSSSS!

i definitely agree with this suggestion.

Open list; click the blank section of the line next to the name of the top item in the list; click the blank section of the line next to the name of the bottom item in list; select destination list from menu next to "move selected to:", or click "Delete Selected"

Wow, that's already doable huh?

A shame search results have no tickboxes at all.

Oh well, thanks a lot! 🙂
