app:// linking support in version 8

Hi @blimmer, thanks for this request. This functionality is not currently a part of 1Password 8, and the decision not to allow links to be clickable unless they begin with http or https is intentional. In part, it's meant to prevent situations where a malicious URL in a shared item might be used to execute commands on your system.

With that said, we always want to find ways to support your use case - so I have submitted your request for consideration so our security specialists can discuss how best this might be done. Thank you for letting us know this is a priority for you!
