Improve “Download PDF…” UX

[mattstein]

The order listing’s Download PDF... button should be improved to match the more optimal UX of the order detail page.

Order Detail 👍

The order detail page is ideal with its PDF download option:

1. If no PDF template/format is configured, no button is shown.
   
2. If one PDF template/format is configured, a simple Download PDF is shown.
   
3. If multiple PDF templates/formats are configured, the button’s primary action is to download whichever is configured as the default, with a dropdown menu for otherwise selecting the preferred format.
   

The user is only presented options that make sense given the configuration.

Order Listing 😐

The order listing page is less optimal.

It does only display its Download PDF… button if there‘s at least one PDF template/format configured, but...

1. It always requires opening the download menu and pressing Download.
2. It always prompts you to select the PDF template/format even if there’s only one choice.
3. It prompts for download types that only make sense when multiple orders were selected, which adds unnecessary steps:
   • If only one order was selected and only one PDF template/format is configured, we have to click to open this menu, ignore an irrelevant option, and choose a download type.
   • If only one order was selected, we might download a ZIP file containing only one document which just adds a required step to extract it.

tl;dr

I’d therefore suggest the following changes for the order listing’s Download PDF button:

1. If only one order is selected from the list and only one PDF template/format is configured, omit the … from Download PDF…, skip the menu, and download the PDF document.
2. If multiple orders are selected from the list and only one PDF template/format is configured, omit the menu’s PDF selection.

This would create a more optimal download flow that’s consistent with the beauty of the order detail page’s PDF downloading experience.

Also, can there be a setting to make "Collated PDF" the default? Maybe even to disable the "ZIP file" option?
