Custom Layout Features

Currently, accidentally clicking the trash can next to the custom layout name immediatly deletes the layout. An additional prompt after clicking the trash can asking to confirm deleting a layout would be great to prevent accidental deletion.

When editing a custom layout, there isnt an option to save changes to an existing layout; it just creates a new layout, even if you name it the same as a current layout trying to overwrite. youll just have two layouts with the same name. It would be nice to have the option to be able to save edits to an existing layout or create a new layout.
