Is the a way to assign a chat command to the actions ? 

(TY great addon! )

Until the Dev comes back, you can put this in a macro:

/run if IsControlKeyDown()then LibDBIcon10_DropTheCheapestThing:Click("RightButton")elseif IsShiftKeyDown()then LibDBIcon10_DropTheCheapestThing:Click()else LibDBIcon10_DropTheCheapestThing:Click("RightButton")end

Pressing this button will open the config, holding Shift will Sell/Destroy (depending on if you are at Vendor or not, holding Ctrl will add lowest item to ignore list. I tried to make it function exactly the same as the minimap button but without having left and right clicks.

My first script macro so massive apologies if something goes wrong.
