Agreed, this is one of the frustrating changes to the My Tasks page. I've managed to create a workaround with Keyboard Maestro on the Mac. It's a little hacky. If you can make it to a group call I can show you.
I'd love a printed out list of these to add to our Asana Conventions project or a link in the description in this video! Also, I think they removed the Tab B cats option :(
