Subtasks ident, tags preview

Love the design, but all sorts of functionality issues:

Where are my parent+subtasks? They just show up as individual tasks making this app useless to me.
Subtasks support is crucial!

We need the basic option of seeing our project within a folder. Then with the subtasks to keep them ident (hidden) within the project (parent) and with little arrow click expand and reveal the subtasks.
2do app for reference.

Need to see who is starred, priority symbol/colour, tags - already in the task field (before pressing it). 
Two modes perhaps: minimised - where priority colour the text and u can see a star. expended mode - see all tasks's assigned tags/contexts (I use priority as tags, as they are the same, as I learned from 2do app), priority symbol, due date (without the time, to simplify the view). 

The first two are crucial (!).

Other improvements I'd like to see is a different default view for calendar view, as id like to see in one wide detailed list events&calendars (like in Pocket Informant). 
Also, if a task doesn't have a calendar (often!) then there's no point in showing "none" when pressing on it for a summery. Better just not to have it as it's just take space (from showing more tags for example).
