Hi, I think a feature to attach file in the form would be a welcome addition.

Describe the feature and the current behavior/state.
The feature would allow a "File" type of input, that would take a file and read it (as string is my guess).

Will this change the current api? How?
Yes, it would add a new Form subcomponent.

Who will benefit with this feature?
Extensions developers

Any Other info.
Nothing much. Feel free to ask questions about use or anything really I'll be happy to help.

Thanks!
