I'm a new user, and very much like what I've seen so far.
As I'm putting my app through it's paces, I'm discovering some features I'd like (that others have already requested), so I'd like to add my "+1" request to be logged -- but also include how I'm getting by without it, or what I'm using as a workaround, hopefully only until the new feature gets added!
A task name (as it shows up in "All" or "Today" or any other filtered or smart calendars) that includes a field or identifier for the project that the task is a sub-task of.
My workaround is to name the tasks in the first instance with the project name they are part of. E.g. Project A includes Task 1, Task 2 -- but I enter them as "Proj A / Task 1", etc so my calendars will show tasks as ""Proj A / Task 1", "Proj B / Task 4", etc.
Workable but clumsy, especially as Project and Task names gets longer.
