Interesting; I've never seen a "save view" button let alone any "Discard changes". This is the "Outline" tab, a default; Is that what a view is, each tab? I struggle just to get something I can be productive with, so I don't have time to create special views.
Is this documented, whatever you are referring to?
The heading I clicked only says "View: *All tasks > >" so there was not even any indication it would try to sort top-level tasks in alphabetical order. There is lack of communication as well as the problem I didn't even know what had been done or if I needed to undo until later.
The thing is, if a "saved" view is listing each task and in my custom order, do you mean when I clicked that heading which sorted by alphabetical order, there is no "alphabetical order" mode being saved? It just independently saves an order which happened to be alphabetical that time? Is that why there is no way to change the sort back to not alphabetical?
This is perplexing, from a design point of view.
