WebOS
I have created a webos, here is about it,

1, Added a Calculator which is really works 2, Updated the window style and its header 3, added a google search option 4, instead just one wallpaper, i used a api key to fetch new wallpaper every time. 5, updated the color and design of quick notes. 6, made every css, js, html files separated from each other. it helps to solve erros more fast and easily 7, updated the Guide into a welcome page.
