A few questions about this game.

[Yvresse]

Hi, I'm gonna be living at my dad weekends starting soon, during the week at my moms.
I have a PC, but I can't move it every weekend, it's not really feasible. So I was trying to think of a cheap way to play this on weekends still... Cheapest way I could figure is to get a PS4 second hand, but can I still use my same characters? Otherwise I gotta see if can buy a cheap PC instead. I did see an option to 'backup all character settings' and I am assuming that is for people playing on the same account on different locations.

My other question is, does this game support controllers with extra buttons, like lets say as example, The Xbox Elite Controller, has the paddles at the back. Will that work in this game.

Then I also wanna know, is there a way for me to have my UI setup multiplied?
Like my first character, I got the UI the way I like it, the text bar is in the right spot. The Chat is resized, the double click right trigger makes me get an extra menu. This all took very long to do and I can't remember how to do it all again. Is there a way I can copy it.
I made a new character and it's weird now everything is default.

Thanks
