Please review my webapp: Da Button Factory - create shiny buttons
dpurp: Not bad.1.  On a first glance the interface is a little overwhelming, and I am not sure where to go/what to change first.  Have a single column of options that can be expanded/condensed accordion style (think the Mac MS Word formatting sidebar).2.  Buttons produced are only a single image.  It would be nice if multiple images/sprites were created (that is, a single image file, with multiple images).  The additional images would enable hover and on click capabilities, providing a user with visual feedback that the image is indeed a button, and that it is working.  That being said, you may also need to include the relevant CSS necessary for a user to select the correct sprite in each situation.3.  Having the Undo/Redo on the top right seems a bit unnatural.  (I didn't even notice these options at first; moving them to the top left may be better?)  You might also consider using the standard arrow icons for these options with a text description on the bottom or on the right4.  Other people have already mentioned this, but additional fonts and a color picker would be very useful.5.  The site's layout requires a fairly wide screen.  When I don't have my browser window maximized, the layout gets kinda messed up (input boxes flow to the next line abandoning their label).
