What is this add-on for?

Submodule Diff Viewer helps visualize modified lines of code in commits and pull request for repositories with submodules.

Submodule Diff Viewer add-on helps watch changes committed to a submodule in a standard Bitbucket Diff view as if they're committed to the original repository. It also gives an ability to watch Blame leave comments for more convenient pull requests review.
