Been really busy and was just tasked with looking into upgrading to the latest jquery ui, however I am very disappointed with the button icons as functionality has been removed.
We have developed a few web apps, and many of them have buttons with an icon on the left and a drop down icon on the right. With 1.12 it seems that a button can now only have 1 icon, basically removing functionality.
Why not leave the icons option that consists of an object with icon and icon_position, enabling multiple icons for a button.
On another note (so any admin please contact me to push me) I have written a jquery ui html wysiwyg editor widget using jquery ui icons, buttons, etc. I have been meaning to give this to the jquery ui project, however I just need to do some minor changes when I get the time.
