Re: your posting Switchboard "use of URLs" (link follows this comment)
I am concerned that Switchboard's "open/extendible" approach could be or become Elementary's 'Achilles heal'.
How can the URL system mitigate the threat posed by malicious code injection / exploits?
These "unchartered waters" may represent a deal breaker for people considering adopting or remaining with Elementary OS.
For me, the Pantheon desktop interface is Elementary's killer feature. Please don't kill it - for the sake of a "nice to have" feature.
Wishing you and your team all the best for 2017
