iOS My ToDo - filtering and mark completed

Hello, firstly i want to thank you for rework od My To-Do, it works perfectly. I am using custom field to mark level of importance on my own importance scale.

On PC it works perfectly, but when i want to continue work in iOS it is unusable. 

The problem is, that user is not allowed to sort by custom field. Other options are hardly usable:

Status - i dont want to change statuses

Priority - i dont want do drag large number of tasks

Importance - it is constantly sending me and others messages about change of importance - could this be switched off?

Please, could you add option to turn off notifications about change of priority OR add other sorting options to MyToDo on iOS? I tried to use dashboard but there are other problems like need for clicking "Show all" every time I open that dashboard.

PS: if you would rework MyToDo on iOS, you should also consider add function - change status to "Completed" on a swipe.

Thank you!
