Tasks product debt

1.) What is the idea/improvement you'd like to see implemented?

Here are my 5 improvement suggestions:

1) use the whole window to show the tasks. Some UI element to show that there is more to load would be helpful. Understand that not showing the whole list at once is due to speed of load. Although I'd prefer to wait rather then scroll 5 times..

2) put Categories filter to Archive tasks. 
3) put categories filter to mobile app in general - NEEDED
4) make it easy to unarchive / recover tasks. Same buttons like in regular view
5) enable multiple select in achive, same as in regular view

2.) What problem would this solve for you?

much easier work with tasks on mobile and with archived tasks on both platforms

3.) What are you currently doing to work around this issue?

impossible to have a team sync around tasks with people only on mobile. Can't see only maintenance tasks. 
Lots of manual work with archived tasks
