How to change controller settings in-game?

When I go to the login screen after using the controller for a certain period of time, the login time expires and I am prompted to log in again.

The same thing happens when I use the keyboard.

1. Can you make it so that the login doesn't expire and stays for a certain period of time while playing the game?

2. Or, allow me to change between keyboard and controller in the settings during gameplay. (It's too much of a hassle to go to the login screen every time I use the controller and change the keyboard.)

3. Or, allow me to use the mouse for certain purposes while using the controller (e.g. trading or organizing items).

The controller is very convenient when playing the game, but it's inconvenient for organizing the warehouse, trading, and other content.
