Basic functionality (alarms/cross device) missing from cortana

[PauluzzS]

I notice some really basic stuff that I would actually use Cortana for is missing.

Cortana cannot tell me which alarms I have set (and currently enabled). Alarms are not synced across devices.

Across devices is anyway lacking as I cannot send text messages from a specified SIM card.

I suppose there are many small things missing that would actually make Cortana useful.
