Absolutely crucial and I can't see any other mention of this:
Capacities weblinks to support system URLs such as:
x-devonthink-item://56944CB1-7EA3-480F-8098-CA53E8DA69BA
Which opens an item in another app (eg DevonThink)
Currently all typed or pasted weblinks have the https:// protocol added making it impossible to link from Capacities to information in other apps, despite offering url-scheme links the other way, to Capacities objects.
