We have a contact form on our webpage, where data files can be uploaded.
In the past, it has often happened that senders of the form wrongly assume that the data upload has failed because they do not receive any confirmation (a check symbol or similar) that the upload has worked. In the same way, there is no error message telling you that the upload has failed.
I think it would be great to add a little visual, that indicates, that the data upload was completed successfully.
