For everyone wanting to change debuff size, here is how you do it.  First go into your WTF folder, account, your server, your account,  then to saved variables.  Delete customnameplates.lua.
 
	Next go into the customnameplates folder and open settings.lua with word pad or any other word processor and use the find/search button of your wordpad and search for "debufficon" without the quotes. A few lines below the first thing it finds will be ["sizex"]=24 and ["sizey"]=12.  Just change the 24 and 12 to any numbers u want.  The larger the number, the larger the icon. I like x=20 and y=25.  Just big enough to show entire debuff but not to big when u get 8 debuffs on it takes up the whole screen.  Good luck.  Thanks for a great addon by the way.
