This release implements XenForo 2.1 compatibility by implementing styling of the badge to match XenForo round avatars style. This is achieved by adding a new CSS class to HTML tag on XenForo 2.1.x only - v_2_1, and this CSS class is used to tweak the look of the badge. Left Top/Right top locations are modified to show a rounded badge. The locations are supported on mobile as well, but the look may be sub-optimal, so please check how it looks on mobiles to decide if you want to use it. Bottom location is deactivated on XenForo 2.1 as it interferes with the online status indicator.
We have merged the changes implemented by @Nerdface at
https://xenforo.com/community/threads/al-original-poster-highlight.142428/page-3#post-1312925 so if you need these locations you can install this update safely. The only change from our side is that we have removed custom styling applied to style property "Indicator Design", so if you may need to check this style property and see if you need to put any background or text color there.
Please note, that the look of badges is tested on default theme only. Large changes in sizes of avatars or other layout elements may affect the location and the look of badges. Feel free to check the CSS code in the template
aloph_op_ribbon_style to tweak it according to your needs.
