Dropper and Dispensers don't show their directions if the front face isn't visible and also share textures with both each other and the furnace, this pack adds arrows to the sides, in diffrent colours for dispensers and droppers, it also gives the observer a side texture to make its direction easily noticeable too.

inspired by a comment ZactheDragon made while streaming, noting that Vanilla Tweaks has arrows for hoppers but not droppers and dispensers.

hope you find this useful!
