There’s no “X” beside the project name in the multi-select > projects popup if tasks are only in a single project like this one:
That means that when you use multi-select there’s no way to remove the task from that project, which I might want to do for various reasons (e.g., maybe because I only want it in My Tasks now).
If I single-select any of the tasks, there’s no such limitation in Task Details–the “X” is present:
Why is multi-select preventing me from doing something efficiently that I can do inefficiently (one-by-one) in Task Details?
Mutli-select includes the “X” for tasks multi-homed to multiple projects; it seems to only remove in the case of single project membership.
