Hi,
I think there is a bug with manual sorting.
If I place any task in my project to be the first task from the top, than switch to some "Today" or "Inbox" for example and than return to the project - the sorting is gone.
If I place the task on any other position than first - it seems to stuck after returning back to the project - so this is good.
I also experienced problems when I sorted more tasks (and put them on top) everything was messed up after switching back to project.
Please fix the problems with manual sorting - because is't unusable and I still have mess in project tasks.

Thank you.
