I have a vision for a website where users can login, register, and access a list of their own customers with functionalities specific to each user (such as sending an SMS from their registered phone number). I've found tutorials on how to implement the login and registration features, but I'm unsure how to customize the information displayed for each customer. Can anyone steer me in the right direction or recommend a template that already includes this functionality? So far, I've only managed to create a basic site on localhost with a simple login and registration form.
