This would also be useful for samples files used to reproduce bugs and screenshots.

Agreed.  This is almost essential for easily integrating bugs and feature requests into our pipeline.  The link to a url is just not as useful and requires a few extra steps.

Agreed.  It would be very handy especially for testing and QA jobs.

For my needs, it is ok to use the url link to access related documents.  However, there are two issues with the url feature.

First is probably a feature request: more than one url link per card would be great.   To be able to define multiple url links in the description text would be ideal.  The down side is that access to multiple linked documents by right clicking a card (a great feature) would be problematic.

Second is a bug: When I have 2 cards each with a link, the links get confused between the 2 cards.  Card1 has a link to "Executive Summary" and Card 2 has a link to "Press Release".  On a freshly re-load board screen, when I right-click on card 1, the "Link to" item is correctly labelled.  Without selecting anything, if I then right-click on card 2, the "Link to" item is correctly labelled.  All subsequent right-clicks display only the second link-to label, even on cards that do not have a url link and that link is active on all cards.

Anyone else out there using the tool for their recruitment process? I would be curious about the workflow lanes, metrics and other learnings you've had.
