"File Input" node updates

Update request - after file is uploaded to show: "File Uploaded! Click here to Upload Another File" instead of "File Uploaded! Upload Another File", it seems it isn't clear for first time users.

Can file upload limit be set by node parameters? 1MB is too small

Have you provided an initial effort estimate for this issue?
