I have two good (and much needed) suggestions for CRED file upload fields:
1) Show a preview/thumbnail of the image immediately after it is uploaded– just like how Types Image field does on the backend
2) If a user is uploading many images (repeating fields) and/or file sizes are big, there is this spinning wheel gif appearing in place of the upload field. Would be better to include a counter bar (e.g. 5%… 25%… 90%…) in order to make it clear for the user that their action is being processed and it did not "hang up".
Also, when I upload an image, I see a "Uploading… xx%" at the bottom of the browser (using Chrome), and after I submit the CRED form, it again says Uploading… Only after uploading completes, then form will be submitted. Why does it upload the files twice?
I saw a couple of threads here asking for these features. These were a while back. Don't we have them already yet?
I hope to see them implemented soon.
