package.elm-lang.org is great - but what if you aren't interested in finding a package, so much as finding packages that depend on another package? For instance - what if you want to find every elm-review package? Currently, you have to hope that the word "review" is in the package name - but this isn't always the case!.
Enter segakcap: a reverse package search for Elm. By searching for "elm-review", you can see all of the packages that depend on it.
