May be a dumb question but... So I used the mage-like hat for my char and I bought new clothes and put it on but the hat just stayed there.. does that mean all 3 of those acc are impossible to change/take off? Help please

Also i play the non target mode by pressing z (much more fun plus no shooting at nothing when walking backwards) and id like to zoom out a bit. I also wish i could zoom in and look at my/others' characters.. is it possible to change mouse scroll from wep change to zoom in and zoom out?
