Uploaded 200 odd smilies by uploading to the server... then for each 300 smilies, i had to select the same category from the dropdown menu... which is nonsensical and real PIA. There should be option to import smilies directly under a category... or there should be an option to select a category once and it would import all smilies under that category automatically.
Also, while importing, the "text to replace" filed should be an option rather than a compulsion. It can be done latter on at our convenience. IMHO Its not that critical.
