@russian-dima thank you for coming back, really. Well, I was trying to ‘digest’ all this information and to decide where/how to begin. Just visited your latest example and now browsing your source page. I guess I’m only missing the ’ if no file to download, then no download button ’ part of my code but I’m sure this is lurking somewhere in your examples.
(I come from Python. I have a good grasp on what’s going on but JS’s syntax is really all over me).
