[Q] HTC one mini root help topic

Hello, I am thinking about rooting my HTC one mini. I know there are millions of threads on here and Google but I still have some basic questions that I can not find the answer for, so if you could help I would be very grateful.

If I were to root my phone, will the appearance be any different? And also would it change anything unless I actually do it manually?

I do not want to do it and then discover I do not like it or that I am above my head, I know most people will at well do not do it then but I have read a lot and I am curious, thanks on advance for any help.

Thanks
