Feature request: User specific layouts

[OneMoreByte]

Is your feature request related to a problem? Please describe.

I use fluidd on both on a phone right next to my printer and my desktop. I don't want the camera and some other things visible on the phone. I created users expecting the layout to be specific to a user but updating the layout as User1 also updated it for User2

Describe the solution you'd like:

User1 and User2 have independent layouts when they log in.

Describe alternatives you've considered:

Layouts that are per device, maybe the settings could be saved on each machine.

Affected users and/or setups:

I'm not sure who would benefit from this. I imagine its a weird edge case thing for some people with multiple devices or for multi-user setups.

I am in the same situation. I think the big advantage of Fluidd is that you can just use an old phone as a screen next to the printer, instead of buying and configuring a new screen for RPI. I think the most common way of working with Fluidd involves a desktop computer for the main setup and a phone / tablet as the screen next to the printer. Therefore, it would be very useful to be able to set the page layout for a user or a device.
