I am considering the premium version. One thing I'd like to be able to do is add a contact to a to do, so that I can dial them directly from the reminder. Is this possible?
That's partially possible. You can't add a contact to a task meaning - you can access a list of contacts and select one, but you can add phone numbers into task notes and all numbers in a note should automatically become dialable when tapping on them.
I'd really love to see this feature as well. It's incredible helpful. Please see my attached mock-up.
This is THE feature I need!
That does indeed look like it would be quite handy! I suspect the challenge in linking a contact is the cross-platform nature of the app. If you select your iOS contact and then try to view it in the Outlook plugin or Mac app or somewhere else, that same contact may or may not exist, and may not match up that easily--names can differ slightly, etc.
A compromise would be to use a platform-specific contact picker like your mock-up, and then have the app embed the contact details into the note instead of the contact itself, and that way it's just text that will be available on any platform on which you view the task.
I think this would be very handy indeed!
