Hi.
For your information..

If clicking on your own avatar in your profile, the dropdown is far away (over 100px below avatar) from avatar
i added this lines in my template css:

body div#fd.es .es-profile-avatar .es-flyout-content .dropdown-menu {
position: absolute;
top: 100px;
}

Avatar images on mobile width are a little bit out of the center, because the img height and width in css is too high. I added this:

body div#fd.es.w480 .es-header-cover .es-profile-avatar .es-avatar img{
width:114px;
height:114px;
}


the ES Online/Registered Joomla module for showing users --> the avatar is also not centered, its little bit too much down.
i added for the module in my css:

body div#fd.es.mod-es-users .es-avatar img{
height:36px;
width:36px;
}
