MyWebClips App - customizable web icons?

I just downloaded this today, and it has some awesome features. The wallpaper is customizable, the web link, email, and phone icons look great. The phone and email icons can be customized with pics from the photo album, and it appears like web icons should do the same. I created some custom icons for websites, but when I reopen the app, the icons have reverted to just screenshots of the site (phone icons reverted back as well the first time I downloaded the app, I deleted and reinstalled the app, and custom phone icons now appear as the custom icon when I reopen).

Anyone else have this app? Do custom website icons work for you?

EDIT: that's MyWebClip without the S at the end in case anyone wants to check it out.

 

Got it! I can't edit the icon after it's been saved, I must edit the icon while adding the bookmark...
