Database fields and code structure have been changed to accomodate with addition of new features for icon customization.
New features:
Username color and usertitle color configurable in the edit user page of the admincp
New user configurability options for Font Awesome icon:
Transformation:
Rotate (90°, 180°, 270°)
Flip (horizontally, vertically)
Animation:
Spin
Pulse
New permissions to cope with the new configuration options:
Select icon transformation
Select icon animation
Icons can now be either displayed before or after username (admincp option)
Note that for users that have the previous version of the add-on installed, a script is run at the end of the installation to import the fields to the new structure for each of your users so don't be surprised if it takes a bit of time.
