Feature Request: Add ability to remove file from input #56
Description
What problem does your feature solve?
When I upload a file to an input field, sometimes I would like to remove that file or "clear" it, but I cannot do that unless I click the input field and select "cancel" in the file selection menu.
One of the reasons this is needed is because if I try to re-upload the same filename with new contents, the new content is not loaded. This means users need to clear the file in order to re-upload.
What would you like to see?
An "x" or "clear" button that allows users to remove files from the input field. Ideally we can also pass a function that is executed when a file is cleared as well.
