I've come with a fairly major update to this plugin! Check it out:
Sprite Button Plugin - v0.8a
Download Now(with example) - 132KB
Adds/Changes/Fixes:
[ADD] - "Compare button group" and "Compare button identifier" conditions added. These will only check if the the group/identifier is equal to the specified value. If you want to see if it is not equal, just invert the condition.
[ADD] - "Override text position" property added for check boxes and radio buttons. This is checked by default. When checked, the "Text position" property in the "Text" category is overridden and the text is automatically placed to the right of the button image. Unchecking this will allow for free alignment of the text.
[CHANGE] - Check boxes and radio buttons can now have button icons. Now that I think about it, I don't know why this was disabled before, but they're there for everybody to use now.
As usual, please leave any comments and suggestions, and be sure to mention any bugs you come across.
Enjoy!
