I have never tried using phone or web addresses in my notes but if its true its quite an oversight and something that should be fixed.
Also, I think, calendar based alarms are a great idea (I would prefer them over push) - however they are little harder to "get". (Even though the technical difficulties related to setting up push and calendar are apple's decision - I believe user ends up blaming the app !!)
While I will ignore the OP's negative tone - I do hope the product team realizes that the product is now pretty damn complex and it is very hard for a newbie to set or explore what it can do and how.
As a point example - I think the sync choices are unnecessarily complex and were driven by engineers more than users.
There should really be only two options to sync:
- omnifocus run server (automatically set up, free and tied to your serial number of purchase)
- a "hidden" webdav option
