that is a helpfull tutorial, but this feature has a somewhat different scope, for example if you wanted to do an effect on the finished texture, it would currently break the tileableness, or if you wanted to create a concretey texture by mixing together cloud layers and doings effects on them, you would then have to do some more work on it to get it to tile, because the clouds feature doesnt produce tileable images either.
By RFE i mean request for enchancement.
