I need to be able to enable checkboxes to remain in view - checked or unchecked after someone has exited the browser, then returned. I have used the 'Hello World' tutorial for saving entered textbox input, but I can't get the same kind of process to work for checkboxes. Is there a tutorial to help me do this, or can you offer any guidance. I am new to appery.io so as much detail as possible will be appreciated. Many thanks John.
