Can I modify Saved Searches?

Or I have to delete it and create a new one?


No, you can only save a new search with the same name (without deleting first).


@Rumo How about put a Drop-down list (like search box) to show all names of Saved Searches? That we don’t have to type again.

I think that’s a bit too much because you usually want to save a new one.
But I think adding the option to overwrite a saved search with the current search to its context menu is a good idea and should be easy to implement.
