Sweet dude,
I like using them for things besides text, even if they are a blessing to type. I like using displacement maps to make images look how should I say "odd" in contrast to the image on top. Say for instance I use cloud render, duplicating the layer, sticking it on top then displacing itself with itself along with a blending mode.
Displacement maps are one of the best filters (IMO) since they are images manipulating other images.
