All those improvements and the Mail experience is still lousy when you need to quickly move messages to folders. I have been relying on MsgFiler[1] for years, but it's been over two decades and Mail.app has not improved much (and mind you, I still prefer using Mail.app over anything else on a Mac). Thank goodness we still have plugins.
