adding steam gamer id and listing the all games of account

[harun-kartal]

so that we can see up to which size we can compress the games in our library and not see a huge list of games we dont know

if app has problems with internet connection then a way to copy that we can export our whole game list and picking steam game ids from page or something like that might be nice
(e.g. there is a empty box says export your game list with (?) and when you click or hover at question mark it says the go to x website(steamdb account page perhaps) expand the game list from 50 to all and copy the whole page(ctrl+a+ctrl+c to not mess up) and then insert here sort of procedure )(then the app would cut the unnecessesary parts and then clean the parts with game ids and acquire all of the game ids from there)
(it would be nice if you can find a way from steam family=adding more then one account)
also manual game id removal from the list might be nice as well
