Please can you make the hyperlink column type accommodate any URL, not just web addresses?
For example, my organisation uses Configuration Manager. Configuration Manger provides Software Center, and applications in Software Center offer a "share" button; here's what's behind that "share" button for an app I use;
softwarecenter:SoftwareID=ScopeId_3B3F076E-EDBD-44B0-81EA-F1958D42C503/Application_185a28f5-a549-4d85-946b-b1f29abdf6fd
A while back, I wanted to create a [modern] list of applications. I would have liked a link that would actually install that application [if your computer had Configuration Manager client]. It worked! For a few seconds. Then, something somewhere converted it into a http: link. Which doesn't work. So disappointing!
Similarly, if you have OneNote installed, it installs an protocol handler for the onenote: URL protocol. I might want to create a link to a OneNote notebook that opens in OneNote, not a browser. I can't do that today with Microsoft Lists.
The roadmap is envisages a mobile app; which is great! Being able to handle diverse protocols really comes into its own here; some very basic examples:
mailto:fred.flintstone@bedrock.com
...would open a new message
sip:wilma.flintstone@bedrock.com
...would open a new chat
tel:+15551234567
...would open the dialler
linkedin:wilma.flintstone@bedrock.com
...might open Wilma's profile in the LinkedIn app
I appreciate that URL protocols are practically infinite. That makes error handling practically impossible. But they have a place, and they are useful!
