yah!!!! here are 2 options. *this does not change the order

this ones for just the user being big:

#sidebar.sidebar > .side-nav > li:nth-child(2) a > img {
min-width: 100% !important;
max-width: 100% !important;
max-height: 100% !important;
margin-right: 0 !important;
margin-left: 0 !important;
}

#sidebar.sidebar > .side-nav > li:nth-child(2) a {
text-align: center;
}

this ones the specific one i use where it makes the user big on the user page and the character big on the character page:

#sidebar.sidebar > .side-nav > li:nth-child(2):not(.user-name) > .display-user > a > img, #sidebar.sidebar > .side-nav > li.character-name img {
min-width: 100% !important;
max-width: 100% !important;
max-height: 100% !important;
margin-right: 0 !important;
margin-left: 0 !important;
}

#sidebar.sidebar > .side-nav > li:nth-child(2):not(.user-name) > .display-user > a, #sidebar.sidebar > .side-nav > li.character-name a {
text-align: center;
}
