I have never given a product 5 stars before. This one has incredible features. I didn't rate the support or documentation because, in my opinion, you won't need either one.
You can create text using any of your installed (Western) fonts, style it in any of over 70 styles, many of which have sub-styles, change the color of the text, background, and shadow, set the angle (separately!) of both the light and the shadow, set the depth of the shadow, add glow, gradients, set the font size AND overall image size, and probably many more things I haven't tried yet. I haven't even tried the buttons and arrows and other icon things yet. And it all renders in less than 5 seconds on my G4 400MHz! Then you just export the resulting image to the clipboard.
I can't find anything to complain about or even suggest improvement on. At $30, this thing is a steal.
