This is great indeed but very limited, it would be nice to be able to pass more parameters to file base.
Also very sad that the free file base does not have more field for its frontend file upload widget.
At the moment I have the two working together using WP File upload short code in a widget and sending info to file base.
Not ideal but works.
I still have that issue for #1 – with the paid version and do not use double quotes or brackets
