Testing smart contract

why was it important to approve it though? was it just to limit how many tokens can two different accounts transfer to each other? If yes then is doing this important?
total supply is declared as a function in the interface, but in the contract declared as a statevariable, is that a right way ?
if approve is like a cheque, then once the cheque has been passed it cannot be passed again right i.e. once the transferFrom() has been called, the amount should decrease in the allowed[from][to] as well right?
When i try testing the transfer function to send tokens to another address in my metamask i.e testing with the send button...the loader keeps loading forever
Please tell what is importance of approve as we can do same thing with transfer function without any checck
