While dreaming about the neat "Multiclick" feature I had an epiphany about including "Button held" into "Button Chording" via the "Unblock after" option. Say you've set Unblock after 300ms, then instead of sending "button down" it might abandon the chord and start the "Button held" timer so if you release the button shortly after those 300ms it does the first "Button held" action or you can hold it a bit longer for the next one and so on… Additionaly you can use the "initial" button for "click&drag" by checking the "Abort when the mouse moves" option
It’s not as good as adding "Button held" to the chorded button but it surely will be great because that way both features are combined in one and you don’t need to chose whether to use the button for only chording or only "Button held".
