While you can't change the Sample text, you can have your font/logo selected in the layers panel and it will auto-preview as you roll over the font names in the font list.
and how do i do that ..my font logo selected in the layers panel and the auto preview as i roll...
I suggest Adobe change the sample word option so we, the users can type in any text and it will appear as we roll/scroll down the font list ..it will give ahigher creativity to those of us who design logos, posters etc...
Oh now i understand what you say..... select the logo name in your file and when you scroll the font changes also..Yes this i know....BUT if you dont know what looks best ..an easier way with be to simple give us the option to use the word sample..
