You do have to remember to use it, but the thing to keep in mind is that you can pipe a list of ANYTHING into it. Any list of text items you can search through with a text query is fair game.

   git log --oneline | fzf

for example is one of my favorite tricks. Instead of scanning by eye or repeatedly grepping to find something, it's a live fuzzy filter. And depending on how deep you want to go you can then add key bindings to check out the selected commit, or preview the full message, or anything really.
