I've a 8.2 Place customized with a folder list that shows a thumbnail used to download the document attached image. The thumbnail replaces the download button.
Now I'm going to upgrade the quickr from 8.2 to 8.5 and I'd like to reproduce the same feature.
Could someone put me in the right direction? I read something about the new widgets architecture, but I'd appreciate very much a good starting point. I'll share with you every progress in this customization.
Thank you in advance.
