[Plugin: OptionTree] Category Text Widget

Hi Derek,
these past two days, i’ve been learned and read about option tree, but still don’t get it all.
Could u please give me a help?
Is the option tree can make something like category text widget plug-in? So u can create same text for every post with the same category? If it do, kindly please tell me how.
