it might be helpfull to have a task reminder within the app, in order to alert me about something that should be done at a specific time. So, even if I am away of my office (inside or outside the building) a beep and a message on my screen would be enough to "alert" me.
i.e. Call John steward
I am aware of google calendar integration and emai alerts, but still would love a simple task reminder within the app, without the need for extra software services.
Also such feature could be accessible offline, in cases I can't reach internet.
