Title: Added show, hide, remove to checkboxes, sliders, and toggle buttons

Added convenience features to show, hide, and remove checkboxes, sliders, and toggle buttons

document.getElementById('theid').show();
document.getElementById('theid').hide();
document.getElementById('theid').remove();

I've just noticed it looks like the user sekkalhidaya has also created methods for sliders as well with some more functionality (enable/disable). Perhaps their code would be better to go with once they make the request for the next branch instead of master as it looks more complete :)
