I add the hide-list props and provided docs and cases in the uploader components. When user need render the file list, they can hide the list and render the list thenself.

Maybe slot is more appropriate. But i think it's more unrestrained now.

Ok, good idea.
This pr will be merged after the next version release and you should update snapshot.

The other submitted files have been merged into my fork, so I seem to have overwritten the code of image preview in the middle. I'm sorry
