I'm guessing this is much the same as the embird iconizer?
It shows a picture of the design in place of the pes,pcs,hus,sew,vip etc icon.
I don't know what embird iconizer is. By the name it sounds like it could be comparable.
I have thumbnailer. No program to open for viewing tiles or thumbnails. I go to My Documents and the screen is filled with images. Makes easy work of deciding what to embroider. W/Embird, you have to open the program
