File upload settings

I really like the flexible file type filtering for files. However it would be great if it was possible to have additional settings such as size (width & height) restrictions for images.

Also, it would be great if tokens could be used in the upload directory as well. Being able to use for example UID there would be very useful.

I am not particularly fond of that the subfolder webforms is mandatory. It would be better if it is just the default value.

I am working on a form that only authenticated users will be able to fill in. It contains file upload fields and I would have preferred if I could have been able to set so files are stored in for example ...files/users/images/[uid] and thus save quite a bit of work manually having to move them...
