Right now I can do most of my Asana workflow from mobile, albeit slowly without multi-select, with the exception of some subtask-organization.
A drop-down menu item to associate a task with a parent task or remove a parent task association would be amazing. Adding to a parent task and converting into normal task are the main features I can’t do on mobile that make me have to go to the desktop intermittently. It would also get around the lack of support of those two features for projects within the board layout.
