Ability to sort both folders and list alphabetically

n think of a sorting option like this, puting the buttons in the first row where users can sort folders (in case of folder view) and list (in case of list view) , based on A to Z or reverse as well as based on ascending or descending order, or a combination of both. Also we can add expand all folder to show lists inside all and collapse all folder. In case of sorting the default view option (the order in which someone has customised its folder and lists inside folder is) must always be there.
