Change the file name before it is downloaded in Qlik Sense
Customers would like to add a file name field to the export image/ppt/pdf dialogue where the user can give the exported file a proper name. As it is now, you will get a cryptic file name when you export sheets/stories. Most likely is that the end-user will change the file name when the file is downloaded.
The default name could be the name of the chart/image/sheet/story followed by date and time.
