A feature request I suppose, unless this is currently possible and Im just too dense to see how to acquire the functionality.
I know, I could use the keyboard commands for such task as “SpamSieve - Train as Spam”.
But I wonder if it might be possible sometime, to have a button that could be added to mail’s toolbar for the two most common actions, i.e, train as spam, train as good".
For me, this would be a little more convenient. I’d seriously think about getting a more button-featured mouse, where I could assign these two critical actions to the buttons - the logitech I have now unfortunately has just 5 buttons and they’re all being used now - hide apps, spaces, etc.
