I have updated the TR View module in the 3.4 Beta update centre to version 3.4.1.2.
The notes editor should now allow you to enter links for any URI
(e.g. notes://blah/blah or xyz://blah/blah)
When a link is clicked, TR will attempt to launch the default browser to display the URI. If the default browser is not able to handle the URI, the application registered for handling URIs of the that type will be invoked.
Please let me know if this does or does not work. Note you may need to register an application to handle the URI scheme (e.g. notes: ) on your system - not sure how to do that.
