How to include the card title in url?

[jose-luis andrade]

Worked in a project where all cards url included the id plus title, which i found so usefull to get info at a glance when recieving multiple cards on an email for action.

You'd need to rewrite a huge swathe of JIRA's core code (And add-ons) to do that.

Where are you getting this "multiple cards on an email" from?  That would be easier to modify to include the information you need.
